Update: It is now 24 hours later and I am now in agreement with Craven. The new site kicks the old site's ass once you start learning how to use it.
Those tags stop seeming unintuitive almost as soon as you start actually using them.
Surfing from topic to topic using nothing but existing tags is bottled lightning compared to going back to the starting line after each perusal.
Disappearing threads and posts that don't interest me gives me a much liked, tailored, jump station for the old fashioned type browsing.
The wormholes between posts-and-answers kick ass too! I do miss the quote feature (I know, it's coming), but I'm sure I'll find myself using it less when conversing with others who fluidly use the wormholes... as they will be unnecessary much of the time.
Seeing High rated posts to draw my attention to a funny Gus, Sad Joe, or interesting Soz thread is handy as hell.
Very negatively ratings on spam, porn, crap threads will be a timesaver too.
With the other already planned improvements and restoration of PMs this place is going to be awesome.
Conclusion: This site already
I am now convinced that those who don't think so just haven't given it a chance yet. They will be happy when they do.
Thanks Craven (Don't trouble your busy self with a reply)
