OK, I suppose it's time to jump on the bandwagon. I've avoided publicly giving out Gmail invitations for a while, but I've given out about 10 of them and they keep giving me more. I've run out of people I think would be interested in them. If you would like one, leave a comment with your email address and I'll see about getting you one. If you're using Hotmail or Yahoo, I'd highly recommend it as a much better alternative (having used them both at one time or another). I'd also recommend it if you use multiple computers and don't have a way to keep your email synced up.
If you're gonna leave your email in a comment, you probably ought to obfuscate your email address to avoid spam. I suggest doing things like spelling it out (bob at bob dot com) or something that requires a bit of human intervention to figure it out. I do get alot of crawler traffic.
