I've already posted in a few places, but thought it mightn't hurt to at least introduce myself.
I'm a fairly long-time linux user now. I'd call myself at an 'intermediate' level of knowledge (I know about acls, the setguid and setuid bits, and such, but not much of the really higher level stuff). First tried Ubuntu back with 6.06, which didn't like my computer at the time, so I let it be. then tried 7.04, which sorta worked... It wasn't until 8.04 that things became truly usable. I tried Kubuntu at this stage (of course, this naturally was one of the more hellish releases for Kubuntu).
I've moved around a little, trying Fedora (which wouldn't see my Windows boot), openSUSE (which was nice, but I learned quickly that I don't like RPM-based packaging), I've booted Slackware in VMs a few times (and been impressed - it really is a well thought out distro), PCLinuxOS, and a few others. I kept coming back to apt-based distributions though.
Then came Ubuntu 11.04. Unity breaks too much, so I installed KDE, which I like, but it was glitchy (regular KWin crashes). That's basically why I'm here - I decided to move to something more grounded in Debian (LMDE). I'm impressed so far. Aside from some issues with PulseAudio (not the first time, I'll add. This was a constant issue when I was using openSUSE for a while) and initial issues getting NVidia drivers to work (smxi/sgfxi fixed this - what a great bunch of scripts!) Everything's pretty much been smooth sailing so far - and I'm tracking Sid!
I expect breakage at some point of course - I'm no fool. But I really like the setup here - the theme was almost exactly the look i was after, nearly all the apps I use were installed as default (VLC, etc.). About as close to perfect. That LMDE's a "rolling" release suits me better as well. No more pulling an ISO every six months (fingers crossed).
