I am not averse to taking fic requests. I have even been known, on occasion, to solicit them, particularly for drabbles. However, I think a distinction needs to be made between the term "request" and the term "demand."

Neither I nor any other fanfic writer is under any obligation to produce fic on demand. If we do not update a multi-part story for a while, we do not owe anyone an excuse. Sometimes real life interferes; sometimes we're busy with other fics; sometimes the fish just ain't biting. That's our business, and no one else's.

As for requests, I do feel a sense of obligation towards those, but only to a certain extent. If I have to choose between something I'm doing as a favor on the internet and something with a deadline in the real world, I'm going with the time-sensitive material every time. The request will be done when it's done, and that's that. No more apologies, no more excuses. I am a writer, not a machine.
