At times, this place can be slow, but there's probably just a lot of people lurking and collecting information. Activity can sometimes be a bit of a ruse--at other car forums that I'm at, some of them are just the typical same old questions (mostly repair ones) asked again and again, and although this place certainly has that, what I find is that the people on the other forums are the most likely to sign up for a couple of days, then get their information, and then never be seen again. Slow can be good, too, because I've seen other forums with tons of activity, but with a lot of idiots, where you never want to go back there. For example, depending on the Mustang forum, you can get a lot of arrogant people. The users here, in contrast, typically are repeat posters, where they're both giving and taking information and needing help and giving out help, as well.
There's a reason why I personally have my membership set to "recurring"......over the course of a year, the information shared here is invaluable, even if on a daily basis it may be slower. The quality of person that posts here is sort of like a fine wine--it takes wisdom to like these cars, you know? I doubt that there would ever be a massive amount of activity here, but again, it's quality, not quantity that we should be after.
