Which Linux Install Should You Start With
I do a fair bit of programming and web design, and since re-installing Parallels on my machine I thought I'd go ahead and load up a couple other systems for testing environments. OS X and Windows I'm fine with, but when it comes to Linux though, I'm a bit at a loss, as I know a couple buzzword builds that you always hear about, but I have no experience using it at all.
Under the circumstances, what distribution(s) of Linux would you recommend?
