not in any particular order

to offer a helping hand if I can (or think I can);
to lighten the load by making people smile if possible;
to ask questions to resolve my doubts, fears, & occasionally curiosity
to get help with alternative viewpoints to things I only see one way
to congratulate or say my admiration for courage & growth in spite of obstacles
to feel myself less alone on a strange and difficult path
to opine on this weird process of therapy
and any number of other things.

since the thread is "what do you want from posting" - when I start a thread asking a question, it's because I want people to respond to that question... when the discussion gets hijacked, yes even if unintentionally (which happens very often & certainly not just to me), the original question gets obscured, or often lost entirely, and I find that very frustrating. If one or two people want to go down a related path, it's not hard to start a new thread, it would be nice if people could do that a little more often. just my $0.02
