what do people use TF for?

Yes but there were about 250 views.

I think this is normal in any system calling for information/opinion exchange: I certainly recognize the pattern from online and f2f classroom teaching and lecturing, as well as years in newsgroups. Most people lurk.

Composing a cogent, well-written question or reply takes more time and effort than many people care to spend, especially if there's no obvious reward for doing so.

Reading a forum post that's longer than 120 words: well, that tends to be too much work, too. (I regularly discuss this with my writing pals on LI.)

Ultimately, though, you can't say decisively what the other 252 openings of this post led to. Except that only 2 people have taken the time to discuss your question with you.
