I'm always working diligently. What happens on user requests is that I "keep" the message. If it's something trivial that I can knock out quickly between other more pressing tasks, I might do it right away. Other things have to be vetted by the rest of the guys as to whether it's a desirable change. If it is, then it gets put in the queue and assigned a priority.
For what it's worth, the queue is pretty impressive at the moment. Don't think I'm ignoring you just because some change you've requested doesn't happen over night.
I may have completely different reasons for ignoring you ;)
