To be honest I don't even remember the old design. That saddens me for some reason.
This is really the only programming website I go to. I frequently Google coding problems and as already mentioned, Stack Overflow seems to be incredibly popular nowadays, so my answers are solved there 99% of the time. I wouldn't want to discuss programming there, though. I'd prefer to do that here. Also, as some have mentioned, I owe a lot of my PHP and programming knowledge in general to this place, so not only do I feel like I owe it, but it also feels like "home", even though I haven't been here as long as some of the regulars.
