If you're in trouble and cannot find an answer to a question which goes beyond Stack Overflow...

If you have a not-so-usual solution for your problems but need to justify it to your boss...

If you like to think on your own rather than blindly follow "common wisdom" and "profound truth"...

...then 'No Bugs' Hare on Soft.ware might be the right place for you.
