I beat portal a few times, it kinda lost it's replayability, so when I got it from steam, was I ever happy. I went through and got the camera shy achievement, and I started playing some custom maps.
I can't ABH, but who cares? I have my mouse sensitivity at around 13.5 right now, working it up to higher, and I'm getting better at this whole portal game. 
I never listened to the dev. commentary, so I'm running through the game again so I can.
If anyone wants to suggest some great custom maps, or some great maps that show advanced techniques and help you get better with them, that'd be great!
I'm looking forward to making some maps of my own, but not anytime very soon. 
I'll get an avatar up eventually, as well. I promise.
