Here's something I'd appreciate. I dislike checking in from my iPhone (compared to my desktop browser), and I usually know where I'm going before I leave the house. It'd be nice to be able to check in as 'en route' to a location, and then send a text from my iPhone to 'complete' the ckeck-in - thus removing the 'en route' check-in from the stream and adding a traditional check-in to replace it. En route check-ins should never show up in the stream unless they're the latest item (spam!), but it'd be a good way to hook up with people - if you know somebody is en route to, say, Denny's, you could text 'em and say "Hey, mind if I come with?". Also, it'd save me having to try to type any complicated names on the iPhone (web interface *or* SMS), and just allow me to send one character to 'complete' the en route check-in (I was thinking an `@` without arguments).
I want the ability to check OUT (aka "going off the grid") as well as checking in.
Obviously 14 hrs later I am still not at my favorite coffee shop down the street. But I don't necessarily want to say the new place I'm at (home, date, new coffee shop trying to get serious work done). This should be as easy as flipping the privacy switch on the homepage or clicking the lock button on the upper right of the iPhone interface.
I love your service and love that I get to watch it evolve daily. Keep up the kickass work!
Wish there was a place to update my location on my profile homepage. I logged in, and can't find a link to enter a new location, which is the entire purpose of the site, isn't it?
It would be fun to have an "I'm feeling lucky" feature (ala Google), where you can checkin via SMS with "@ businessname 1" or "@@ businessname" (or something else) and that would automatically check you in at the first result for that business name.
(I can't take credit for this idea but I'm submitting it anyway :)
