The answer is, I don't know how to use my freaking phone. I've only had it for a couple months. I must make a mental note that checking into places doesn't have to be done on Yelp. Although Yelp is cool, Facebook seems to have an easier app for such tasks. In Yelp, I must start the mobile app, search for the place I'm hanging out at, then press the 'check-in' button and follow thru to make sure it worked. I might even be prompted to write a little something.
A widget I already have open in my desktop will pinpoint my location so that all I have to do is rabble on about what a good time (or not) I'm having there. Easy. I'll try to remember that for tomorrow.
