Hey, listen, even if you don't approve of Twitter, this is a good thread for newbie writers. Shannon Stacey (whom I love even if she ignores me 99 percent of the time. No, it's ok. I don't mind) started it. You just go here and type in #writeradv . Easy!
And unlike #queryfail, there isn't a lot of meta-discussion so far. If you look up #queryfail there are thousands of messages about the process and how meaningful/horrible/innovative/boring it was. Not worth the time. Better to read about queryfail on a blog where the good messages--as in useful or funny--are collected.
