I've been trying out the Linux alpha of Google Chrome. I started on Monday, June 8 09:40:37 MDT 2009 with version 18.104.22.168 . A month and a half later, it's at 22.214.171.124 . I haven't had any crashes. That's not bad.
I'm trying to switch to it, not because I'm unhappy with Firefox, but because it's the only way I ever learn new stuff -- by forcing myself to use it.
