Blogger Board Domain Madness

A couple of hunter bloggers have installed discussion boards lately. The outstanding one is obviously the BRK board. 400 Members, 2k+ posts yet. This one may become a replacement for TKAsomething and the Elitist Jerks as far as hunters are concerned. Obviously, it is the fact that BRK is (in)famous among hunters in WoW that makes the masses head there.
Mirshalak and Pelides are heading in the same direction, but do not have more than 4 registered users each up to now. What do you need first to get an active board? The board or the community to drive it?
The official forums do have a huge community for sure. But my own experiences and taught me that a huge community must not always be good. In fact, there are too many trolls around and the little bit of good information to be found there is in most cases masked by obscure thread titles or hidden in between flames. So size is not the only thing that matters. Quality attracts quality and accumulates to size. I sincerely hope these boards don't get trolled too much. And I hope for Pelides and Mirsh that their underdog boards get some traffic as well. Problem is: If I discussed the "what is the best hunter pet" questionin one place already, I might not want to discuss it over again.
An idea is born: Is it possible to have some kind of, let's call it meta-board? I mean blogs link each other's feeds through RSS. This enables us to collect posts in a third party feed reader for convenience. What if there was a technical way to feed a whole thread from board X to board Y and from the point both board moderators agree, be able to reply to this thread in both boards, and feed the replies back to each other. Come one, brains of the internet, that does not sound too difficult, does it?

Another trend I realize in the blogs I read, is migration from Blogger towards Wordpress, and a developing need to register own top level domains. Blogger is a free service, easy to start off with, and almost fail-save. Custamizing Wordpress on your own domain is a much bigger task. I appreciate anyone who volunteers to pay a webhosting bill and designs his blog / site in a way that differs from the masses. If it breaks my reader, I am fine with it and will repair the feed. But wondering whether to follow and do the same I decided not to. Blogger is not top notch, but still convenient for me. And registering a domain is something that I am not willing to do for two reasons:
1) It costs money
2) It would reveal my real-world identity
Number one is obvious. Number two is besically because I don't want my flesh and blood to be targetable for something my virtual avatar has done or failed to do. This does not mean I don't get engaged in real-life as well. I do attend guild-meetings, but I decide who gets my phone number and address. I don't want anyone to be able to type "Xizang" into Google after a lost Arena match (nearly impossible to lose against my PvP-noobness anyway), find the site, lookup who registered it, and decided he could be here to challenge me before his anger has settled.
