I think views from the forum help things. I think all views help increase your visibility on both etsy and google. I'm not an expert on these matters, so someone who might be, correct me if I'm wrong. The more attention to your shop, the better, whether those views are from potential buyers or not, I'm sure it doesn't hurt - further down the track it must help build up your shop. Lots of favourites, etc, make the shop look even better to a real buyer. Not being able to participate in the forums is a bit of a disadvantage with all that, I must agree.
I also agree that the forums do have a lot of repetitive themes and a few dim-witted posts going on, and most of the threads I saw yesterday looked pretty boring. I browse the forums for a bit of entertainment as well, and there hasn't been much of that lately. Plus there's a fair bit of useful info at times. Even if you're muted, you can still read what interests you.
Teams can offer some better quality conversations, that's for sure.
