It depends but a smaller social focused FC might be more of an interest to you if nothing else it can help you get better integrated with the people there and actually overcome the issues(or atleast expand your circle of people you know to make it easier). You'll actually get to know people and the shyness should get reduced a lot(I never was much for FCs(social awkwardness here) yet here I am more than a year later, went through 3 and am now one of the co-leaders that the people I played with(in some cases over a year now) have setup).

But yes you can just delegate the FC chat to a different tab so you don't see what's going on in either case.
