Stop saying Thank You too early in a thread. This is the equivalent of "I've got what I needed, I ain't coming back here no more". This manner can be interpreted as "curt" in real life, and will totally limit and inhibit even those who want to talk to you. The ability not to turn people off is how a friendship might start. Just relax, and let the world happen. Don't interrupt, unless you plan to ask a "open ended question" to have others talk/write more. Be with people. Have a listen, then put in a question. Be helpful. You'd make a lot of friends.
