How manydistributions are there? Do you know? I've never counted. All I do know is there seems to be so many things going on that it could make your head spin.
If you're like me, you might want to head over to DistroWatch.com to stay up to date on all the Linux distribution news. Started back in 1999 this site has grown from a simple table of a handful of Linux distributions to a full blow site that enables you to find detailed information on your favorite Linux distribution. Get news, podcasts, reviews, commentary, package compatibility, you name it, and it just might be there. I've bookmarked this site but more importatly subscribed to the RSS feed.
