@damdamdam:
Yes, memoir.
I did a few live pitches at conferences just to get out of the house. The agent that signed me was one of these - I pitched her last November but she says she couldn't get back to me sooner because she was changing agencies.
I started sending out slush pile queries in January. I sent 10 in January and Frebruary, and then 20 in March. I only got 2 requests for fulls from the slush pile, 2 rejections, and overwhelming silence.
I don't care how busy agents are, I think the silence is rude because you wonder whether they ever read your query. After receiving the offer, I reached out to the others with fulls or proposals (there were some more from live pitches). Most have passed, two are reading. I reached out to some with recent queries I sent but - have been met with more silence.
