Hmm, there are lots of great threads. D21lewis' Dragons Dogma thread is a recent example of a 'great thread' in my opinion. It's nice to see people actually talk about gaming & discussing their first impressions of the game. There should be more threads like this.
A recent example of a 'shit thread' would be MDJ's official Halo 4 thread. Lots of interesting Halo 4 news has been coming out recently that nsanity has been posting & MDJ hasnt been online to update the thread title to let people know that new news has even been released, so a bunch of people are missing out on discussing it. The content is there, but the management of the thread sucks ass.
My prediction threads:
Wii U will sell under 40m units (made on 14th September 2012)
PS Vita will sell under 20m units (made on 30th September 2012)
Wii U will sell under 7m in 2013 - I was right
