Weeplaces updates with filters and friend comparisons

On Friday, Weeplaces — one of the checkin visualizers we featured last month — released several new features that make it more social and help to share the story behind your checkins.

You can now see any of your friends who’ve also used Weeplaces and compare your checkins to theirs. Yours show up on the map in blue, theirs in gray and any places you’ve both visited show in pink. It’s an interesting way to see where your worlds overlap.

You’re no longer limited to your full stream of checkins either. You can now filter by category, location or date to pick out places you ate in New York or spots you visited on a trip to San Francisco. It’s easy to share those filtered lists with friends on Facebook as well.

Further increasing the social utility of Weeplaces is the ability to comment on your own checkins or those of your friends. You can add a review or something you’d like to remember about the checkin. This is a feature that is surprisingly missing from foursquare’s main app. Any shout you made while checking in is automatically included as the description, and can be edited or removed as desired.

In addition to foursquare, Weeplaces also supports combining Gowalla and Facebook Places checkins into a single “geoprofile.”

While we called Weeplaces a “one trick pony” the last time we took a look at them, these new updates add a new dimension to their service. The social features could make it the de facto hub for all your location-based checkins.
