Sometimes, during some downtime, I'll feel like doing some programming (I'm sick, I know), but I am short on ideas of what to do. Some other times, I'll have a great idea about what would make a brilliant software project (large or small), but won't have the time or inclination to actually make it.
Very briefly looking around, I've seen that there are some "idea exchange" websites (whynot.net) which have some great ideas, but aren't targetted enough to anyone who could actually implement the ideas.
Is there a place where ideas for software projects can be shared?
Edit: I just found a similar question here: Ideas Exchange between Programmers, so I'll close this one.
