I think the response a person gets here when they either just say "hi" or asks a question has to do with a number of factors, but timing seems to be one of the biggest.

I have found that if I post on a Friday night or any time on the weekend, the post will flop. Why? It seems to me that a great many people here just aren't around of weekends. If I post the same thing at 10 or 11 am on a Monday morning, it can soar and get 30 replies. If you make a new post just around the time the weekly bulletin is being e-mailed, your post will pick up a lot of traffic from non-regulars.

Likewise, if you post during a week when everyone is insanely busy, it'll seem like you're being ignored. This week will be particularly bad because so many people will be away at the conference in Phoenix.

And I find that sometimes you need to be tenacious and bump your own post with a "Hello, is anyone out there."

And finally, if the wrong person responds to one of your posts with one of their snarky two snaps and a bag of chips replies, then, if you don't have a thick skin, you may just get the wrong impression and leave.
