>Tip4Commit recently made a change to revert tips that remain unclaimed for 30 days back to the project. So far, according to Gasparyan, about 20% of the value of all tips have reverted back to their projects.<p>That might annoy me, if I had sent any tips, or if I had received any. Not that I am opposed to supporting T4C but I think 90 days would be more reasonable, and I also liked some other HN user's suggestion that people be given the option to elect a charity or other project to receive funds.
