Oh, nothing wrong with it. I use them too. May sound crazy, but they all tend to be MVPs answering the questions. Greater variety in EE.
It really is difficult to explain. Maybe Adam can shed some light. In the threads you are talking about, one's question kind of gets lost in a sea of other questions, and you may get one, two, or three responses. You generally don't get a lot of back and forth.
In EE, it isn't uncommon to have a question with over 100 comments lasting ten days or more. The search is way better. Overall, just a much better forum for that type of thing at least for me. For some reason, they seem to have designed a much better aesthetic forum that makes it a lot easier to read and understand.
