Her PM entry says, "I will respond to you. Forgive me in being brutally honest, but I may respond immediately or we may be enjoying a different season when I get back to you."
This is common with many agents. Between all the regular work they have to do, they will often set aside some time to work through a backlog of new queries. This time might be every few weeks, or even every month or so.
So it's not something to worry about just because you haven't heard in a while when someone who queried two weeks ago got an immediate response. The other guy might have gotten a query into the middle of an ongoing session, while your query is waiting for the next one.
I like that she's in Hudson, WI. My wife grew up there, and her family lives in River Falls.
