I just picked up my secondary computer and logged in on this blog. The first thing I saw was WordPress telling me that I use an old browser. Since Safari 5.1 is out, apparently 5.0.5 is considered old. This is a fairly aggressive mode (I prefer to see things like IE6/7/8 and Firefox 3 as old) but I love it.

Good work WordPress! Anything that make people update their browsers more often is great.
