I felt my first earthquake about an hour ago! It was weak here---there was a brief creak and then the whole building shook for, like, two seconds. Just long enough to make me pretty sure I hadn't imagined it. Naturally, my first instinct was to post to imsasun, which I did, and about ten minutes later someone confirmed that they'd felt it in Wisconsin, and then a few more from the Chicago area. Meanwhile, the usgs site was not listing anything, even on its "realtime" maps, so about twenty minutes after the quake I filed an "I felt it" form for an "unknown" quake.
About 1:45 the quake went up on the site; apparently it was a 4.5 just outside Ottawa, IL, and the "I felt it" responses are plotted on a map, which is cool.
