I've been reading the forums for a couple of years now, but don't post as as I don't have burning question about why people do stuff, not great at remembering or telling anecdotes, I'm too calm and drama free ( read boring). Even when i think i could share something, the thread has moved on. That said I love the forums, am amazed at the situations played out and the great advice and life experience shared.
I suppose that why it's hard to move on from lurker to contributor.
