I think there is valuable information and many people that are willing to help still on the site. With the advent/ progression of social media as a whole, there is bound to be more static, however.
If you do a google search on any tech topic, it will inevitably lead back here....most of the problems have been covered multiple times.
Biggest differences I've seen in the 6+ years seems to be:
a) The bash threads (maybe it's just me)...have they always been this bad? I don't really know...never noticed them in the earlier days..maybe I wasn't paying attention.
b) The mod (not moderator) threads...there has never been such a surge in people buying high dollar, 3d stuff before even owning the game. Completely blows my mind. I've seen FS ads of people selling hundreds of dollars worth of stuff, as they lost interest in the game before it came out. I remember debates over switching to led lighting as opposed to incandescent. Now there are development threads for machines you can't even buy. How does that happen
I'm grateful for Pinside and the vast majority who post. If it's changed, just a sign of the times, imho....
