Peekay,
I bet you didn't know what kind of a "discussion" you were starting when you posted your question, did you?
Talking about Linux distributions is worse than discussing religion or politics.
So, since everyone else threw their suggestions in the bucket, I figured I might as well too.
Your best bet would be to try a few and choose whatever you like the best. It's really that simple. The ones you choose to try first should be based on how much time you want to spend learning the OS versus how much time you want to use it.
Back in the day, you really didn't know Linux unless you were using Slackware or Debian. Installing Debian was like a right of passage. Now, with the latest release (Sarge), I've read that it's not nearly as difficult as it once was.
Now the new favorite of L33T H4X0rs everywhere is Gentoo. If you go for a stage 1 build, it's a real pain the butt, which is fine if that's what you want to do. The supposed big advantage is that it's so much faster because it's compiled for your machine. The studies I've read indicated that the performance gains weren't all that significant. You do still get the bragging rights however.
At work, I manage about 100 Red Hat boxes. Personally, I don't care for Red Hat that much, but that's just me. Probably because I hate Gnome (as I hastily put on my flame retardant suit).
At home I've used Red Hat (before I knew better), Mandrake, Libranet, PCLinux OS, and now SuSE 9.2 and 9.3. For the time being, I'm sticking with SuSE. It does what I want it to do, and I like the way it looks.
Really, try a few to get an idea of what you like and what you don't like, and go from there. You might want to check out
Distrowatch. It's a great site to learn about what's going on in the Linux world.
Linuxquestions.org is another good place to visit.
As for html editors, those have been pretty well covered in previous posts. I've used Quanta+ on a few occasions, and it worked well for me. Of course, The GIMP is the big choice for graphics.
Good luck to you. I hope you find the one that is the right one for
you.
