Thanks, I never really considered the option of this being personal, and I am too excited (to use the American lingo) of the ability to ask and get specific answers to be frustrated when I don't get them.
I think the tagging is a mechanism that sucks, but being very aware of its many pit holes (e.g. using different form for a term thus not answering the search criteria), I believe I did tag correctly.
My thoughts were that I either write too specific or not clear enough questions, or that after the initial hype and public relation with the introduction of Yedda, there is now a recession in the number of people actively searching in it (BTW, the speller is a great feature, but Yedda should be in your dictionary). Anyway, I really like your tool, find it useful and recommend it to others.
