Don't mean to be rude, and I mean that truly, but this sounds like a you problem.

I spend every minute of my online time talking to my game friends in my FC or in the 6 linkshells I'm in, and in dungeons I /make/ conversation and people usually oblige. It's really quite nice.

I always found it strange that the people who make these kinds of threads are the kind of people who never engage anyone. If you want to converse and be social, then be social. If no one is talking in your instances, that means by association that you are also not talking...
