Absolutely, HD, giving people something to respond to will get you more responses. The intros give newbies a place to lose their virginity and generally don't get much conversation. Someone says "hi, I'm X and this site looks interesting" usually gets one or two obligatory "welcome" posts, along with a subtle begging for something to clue us in on who they are. I used to greet newbies more often, but don't always have the time I once did.
Since there are always newbies posting in those threads, we don't know what it is they like or want from TFP. From my tilted perspective, the way to become a true part of TFP is by posting. We want to get to know newbies, but they have to give us a chance to know them by sharing ideas, knowledge and opinions on the Boards. Or even, like you said, ask a question. A lot of us love to help.
So although I didn't greet you in your Intro thread, you've begun to dig in a little, so I can respect you and feel more genuine and comfortable when I say: Welcome to TFP! I do believe you'll enjoy it here.
