So, “Trackdropper” may be the most innovative location-based app I’ve seen yet – it lets you “drop” music files from your smartphone in physical locations for other users to “find” and play. Like CNET says, it’s Pirate Bay (or any torrent site, really) meets Foursquare [CNET]

And speaking of new location-based apps, The HotList is a new (somewhat location-based) app that aggregates data from Facebook Places, Yelp, Twitter and Google Maps to tell you what nearby venues are currently popular regardless of whether any of your “friends” are there. It also gives you the female-to-male ratio and any recent Yelp reviews or Tweets [Mashable]

WhereMark is a new location-based type service that allows you to share Google Maps “bookmarks” with your Facebook friends…but it sounds like the service is about as well-constructed as the company’s pitch [TechCrunch]

Hey, guess what? This year’s US Open has an iPhone app! And one of its features (along with a slick augmented reality feature) is the ability to check-in on Foursquare…which of course you could just do using the Foursquare app, but there’s a lot more to the US Open app that makes it potentially worth nabbing [Mashable]

On the new services front, Place Pop has announced a Facebook Places dashboard that you can use to discover what locations are “trending” among your friends using Places, and a complete list of where they have all most recently checked-in. IE – it sounds like using the Foursquare iPhone app [TechCrunch]

Elsewhere on Facebook Places, MeetMoi became the first location-based dating app to integrate with Places (sidenote – I could’ve easily made the “love at first sight” joke here, but it would’ve been too easy) [Mashable]

[TechCrunch]

Previously, Booyah‘s location-based arsenal consisted of the oddly popular MyTown app. But as of yesterday, MyTown is joined by Booyah’s latest app, InCrowd. InCrowd is the first app to work off of Facebook‘s Places API, and allows you to “experience” your check-ins through its virtual world (as you can see above) [TechCrunch]

Broadway’s coming to Foursquare…er, sort of. Pretty soon, Foursquare users will be able to get discounts on souvenirs at live shows (and other incentives to be named later) just by showing whoever is manning the merchandise kiosk their phone screen, indicating they checked in at that show [Broadway World]

With all of these surveys flying around indicating many people still haven’t jumped on the location-based services bandwagon, let’s not forget that many people still don’t even own a smartphone, on which they might use a location-based service [VentureBeat]

Drilling down into yesterday’s NY Times location story, it looks like men between 19 and 35 are the most heavy users of check-in apps [Poynter]

So, if I’m understanding this correctly, Vail Resorts (Vail, CO) has come up with its own sort of location-based social play. EpicMix is an app that rewards users for certain accomplishments by tapping into radio-frequency enabled chips in their lift tickets and season passes (assuming they have those, of course) [Mashable]

Well, while VH1 devises Foursquare badges linked to, you know, music, apparently MTV has devised a badge for getting yourself tested for STDs. And no, I’m not joking. Interesting social study – How many people want their friends to know they’re getting tested for STDs? [AP]

But that’s not all – MTV has actually announced a badge linked to music – any user who follows MTV on Foursquare and checks in to a music venue between yesterday and Sunday will get the MTV VMA Moonman badge (in advance of the actual VMAs, which are September 12). Oh, and in addition to the badge you get entered for a chance to win a trip for two to the VMAs [Mashable]

And as was expected (though a little sooner than expected), Foursquare just hit the three million user mark [TechCrunch]

Four topline observations from a recent “study” probing why people sometimes check-in “off the grid” on Foursquare [TechCrunch]

Elsewhere in Foursquare news – the company told Gowalla, we’ll see your Madison Square Garden billboard and raise you a digital one in Times Square! [AdRants]

Finally, just a reminder – location-based services still haven’t hit the mainstream. And yes, I fully expect to read this story at least once a month for at least the next year or so [NY Times]

You may have already noticed this, but as of yesterday afternoon, Foursquare has changed the way your check-ins look. Instead of just telling you how many times you’ve checked in and who the mayor of the venue is, it now tells you how many days stand between you and mayorship if that number is less than 10 (days instead of check-ins because it only counts one check-in a day per venue towards mayorship) [Foursquare]

As we have mentioned here over the past couple of months, one of the major trends in check-in apps is the ability to check-in places without actually having to physically “check-in” to those places. Well, there’s a new app in the mix that serves this purpose – Checkmate [Mashable]

Defining the “two types of check-in app users” – hyperactive and hyperpassive (the latter of which would be all over CheckMate) [AdAge]

Among Time.com’s 50 Best Websites of 2010 – Gowalla…but not Foursquare…of course, these are more used/valuable as apps, but still interesting… [Time.com]

While many social gaming companies keep their gaming mechanics cards close to their chests, SCVNGR puts its “playdeck” where anyone can see it [TechCrunch]

Speaking of SCVNGR, the location-based challenge app maker has a new partner – Zipcar. Now, Boston-based (sadly, yes, it appears limited to Boston only) SCVNGR users can earn points for completing challenges that can be redeemed for Zipcar merchandise or a certain value of “driving credit” to be used toward renting a Zipcar [Boston.com]

AT&T is working with the location-based service Scvngr to reward customers at 50 of its midwest stores. Customers have to complete “challenges” to get reward points, but the ultimate reward could be $50 off a Samsung Captivate. [Mashable]

In a similar vein – a new startup app called MessageParty would let you identify and participate in any “chats” going on around you, based on your location. So, kind of the same thing except you can’t direct at what location you want to see/participate in conversations [Mashable]

Random, but interesting – “The Top 5 Ways Big Brands are Using Foursquare” [Mashable]

While it lacks some of the features iPhone/Android/Blackberry Foursquare users enjoy, ThinkChange has released an unofficial Foursquare app for Symbian S50 phones (like Nokia N97, N97 mini, X6, 5800 XM, Samsung Omnia HD, Sony Ericsson Vivaz)  [Into Mobile]

Apparently, Facebook Places was working in Canada for a hot second yesterday despite the fact that Facebook hasn’t officially rolled Places out to the region yet, though Facebook vehemently denies that it was…however that works [TechCrunch]
