Best Player Communities

I'm doing some research on building player communities in iGaming, and I wanted to put a couple questions out to GPWA..

1) What are the best casino player communities? Obviously casinomeister is probably one of the most well-known, as well Josh at LatestCasinoBonuses has a pretty active commuity as well, but I'm curious to hear which other ones people think are really high quality. (Hope this doesn't spark rivalry).

2) What makes a player community good? Obviously size and activity level are a big part of it, a base of quality experts who regularly contribute, etc...

3) How can someone go about creating a player community? It's sort of a vicious circle.. you need community to build community... so how do you go about getting around this..?

Appreciate any insight on the above.

BTW this is for an article in iGB affiliate magazine so if anybody wants to get some extra exposure, and has experience in this, maybe we can set up an actual interview and I can give you a credit in the article.

Cheers
