So in a completely bizarre turn I've been asked if I want to take over leadership of the committee I resigned from. I'll be asking some people for advice and getting some more information to help me make that decision.
I'm leaning toward either no or not yet, but I'm standing by for more information, clarifications, or a convincing argument for why this is a good idea. There are some things I could do better, but most of my reasons for leaving wouldn't be fixed just by my taking over because the problems originate external to that group.
Officially turned that down. The other big factor in the decision is that the upcoming deliverable schedule is all redoing (for dubious reasons) stuff that we finished years ago. I'd rather work on new stuff.
