lcarreau has been inspiring me a lot lately .
What is so bad about being inactive? It's only "bad" when you own a batch of pages that people want to contribute to but can't because you don't return calls. Yes, they made the pages once, but that was then and now they've moved on. What do they care?
If they had allowed collaboration on their pages then they could definitely go away without bad feelings from the rest of us. They came, they contributed, they disappeared. In the world of dozens of free internet services competing for our eyeballs, this should be expected behavior. Instead we keep asserting a wish that "if they would only" return and take care of their work we wouldn't have something to complain about. Magical thinking.
Diversity of activity levels is healthy.
