Maybe my memory is incorrect, but they were kind of sketchy; their page implied companies not paying them weren't interested in customer interaction and they wanted $1200/year to get rid of competitors' ads before 37 signals called them out: https://signalvnoise.com/posts/1650-get-satisfaction-or-else
I seem to remember at the time there was about 1/2 year - year where Google loved them and you'd get a Get Satisfaction result for googling "[company name] support". GS were HN darlings for a little bit, then started getting annoying because you'd land on this pointless page, then 37signals (rightfully) publicly called them out, then google seemed to delist them in a panda or something and then everyone forgot about them.
Yahoo Answers is nice and not at all spammy. Some of the answers are bad (and some of them are very good), but the site itself is clear and simple, and doesn't have the obnoxious login nonsense of Quora.
I'm a former Get Sat employee (I left about two months ago). While the company may have done that early on, we definitely did NOT continue that at any point when I was there. There were a few communities like that we still kept up because there was some activity, but we certainly weren't adding new ones. In fact, we were actively pruning communities that had no activity and were on the old, free accounts when I left.
In the 2.5 years I was there, the only communities we launched were ones we were paid to launch.
Whenever I ended up on a getsatisfaction page after searching for something I always felt like I had landed on some kind of dodgy crappy aggregator rather than anything official.
