Well, the old version, like the versions that came before it, is dead and gone, so I don't really have use or time for waxing nostalgic about what was. I'll leave that to you and others.
In spite of all the complaints, there are plenty of ways to customize the user experience here. It takes a bit of time, but, you know, such is life. If people want to make the most out of the site, fantastic. Pretty much every complaint I've seen can be overcome with some digging and tweaking, and I will help continue to help people with that in any way I can.
As you know, there are a lot of refinements being worked on. There are some issues with finding new content that I would like to see straightened out, but otherwise, I'm enjoying the new ASC and discovering its many possibilities.
Good luck!
