There's also just been not as many posts up in SYW, particularly for actual excerpts/openers, recently. Which is natural. It goes in cycles. Last spring there were a huge number. As was said upthread, might be NaNo right now eating people's time. I'd guess there'll be an uptick over Christmas as people's NaNo projects get put up for some early feedback.

OP, try taking a look at the genre-specific sub-forums, most of which have a fairly active first-200-words thread. I find there tends to be more activity there. Also, queries. There are always queries.
