I just found this, and can't wait to try it out. I have one major question and a request for a feature:

Does this use the v2 API for Facebook? I know BarioSquare does not, and that's what I've been using up till now. The v1 interface is slated to go away very soon.

As for the request: Could you have the daemon check for the connected WIFI spot (and/or nearby spots) and just use that if it's something useful, avoiding the need for a GPS fire up?

I ask this because I would love to let this check me in to places, but many times the places I am at can't get a valid GPS lock, and AGPS is very inaccurate in my area. In most cases though, there are wifi hot spots that I'm either connected to or that are clearly visible that would indicate my location. It would be great for it to see my work wifi network and just check me in at work. Same with home, and/or a few other places I frequent. And since just checking which SSID I'm connected to takes almost no power (vs a GPS fire-up), it would drain the battery quiet a bit less.

I'd be even happier with adding an option to only check the currently connected wifi spot (no GPS check) while the app is not running. That would be the ideal method for me, since most places I go have some form of wifi, but are enclosed enough to make a GPS lock hard to get. And the few that aren't are places I could manually run the app at to check into.

Great app though, and thanks for all it does already! I really like the interface, and the ability to group spots from other services into one, and locally correct their GPS spots when they're off a bit on the service! All great features!
