Hey, Hippo- good to see you from the Cubase site. I've been lurking there for a couple of years, but seldom posting.
The reason so many people come here first is that many of them *start out* here before they actually have decided on a product (do a search here for "which is better" topics). This place also offers support on many other issues: mic choices, cable issues, and so on. I hang out on both this site and the Cubase site, but the probelm is that the Cubase site is *too* specific. Yes, you'll probably get your question answered more quickly and accurately there, if it has to do only with Cubase. But here, you can enter into dialogues about many more aspects of the home recording hobby.
This place is also much less actively moderated (see the Dragon Cave, which is basically a honeypot for flames and offtopic discussions), so some people may feel a much different level of "community" here.
The Cubase site seems to be primarily populated by folks who appear already know all they need to know about recording, hardware, acoustics, care and feeding of the artists, and all the other related strudio-centric topics. I believe that the original intention of this site was to be primarily for folks who don't know all of that stuff, but wanted to learn from scratch...
I hang out in both places, and often link from here to there (for reports of upgrade releases and the like). People from here can and do follow those links over to that site- but then they seem to gravitate back here, more often than not. The higher concentration of apparently-"pro" recordists there may have something to do with that. Different strokes for different folks. I don't think it is any reflection on Steinberg's level of support: I think it is entirely a societal issue...
