Bug report: On your front page, when opening the drop-down. If you enter a twitter username as it suggests, ie: @username. You are redirected to http://knowitapp.com/@username which gives a 404.

Do you have a formal place to report bugs?

Thanks for bringing this up. We have a feedback form for people who are logged in. But not otherwise. This is as good a place as any for bug reports, at the moment ;-)
