What kinds of community site is big popular : 1) Forum 2) Social network 3) Blog like blogger.com, wordpress blog My vote is going to > Forum
well social network because it's more personal some things on forum just is not the same on social networks my vote goes to facebook!!!
My choice goes to forum. There is more interaction in forum and also it is more sticky if you have a large base of members.
I think social networking sites are more popular now. The sites like face book, Twitter, dig, delicious etc brings a lot of traffic to your site.
Social networking is the call of the day ! Facebook just rocks ! The interactivity and even the games are just too addicitive !
Of the three, social networking is undoubtedly the more popular. It seems like everyone (including their grandmothers!) has a Facebook account lying somewhere around. Also, sites like Twitter have recently been receiving a lot of exposure through mass media and have subsequently suddenly become more mainstream. I have yet to see this happen, especially not at levels such as these, for blogs or forums.
