Where's all the discussion?

The amount of discussion on IxDA is far less now than it was when I joined 6-7 years ago. Is there somewhere else on the internets with more active discussion? Or has talking about UX just fallen out of style?

I agree.
I used this site heavily for UX ideas when I first started in 2006 and noticed a big drop in UI thread activity around 2010. Most UI threads get very little to no feedback.
