Really, why not? Then again, I used to be like that, too. I get interested in something very fast but there is a point where I am "done" discussing it. Like Twilight, I love the board and the series a lot, but it feels to me like I can't really contribute anything useful anymore. So I lurk...
I am very glad for this board, though, because it's so different from most boards
There's something new all the time!
