madlibber.com is such an awesome idea. You need to take some time to populate (or copy) good mad libs and artificially vote them up so that it's not a ghost town when people arrive.

Here's my contribution: http://madlibber.com/madlibs/21

Update: I just created an account with inqueryapp -- I cannot add a category. The AJAX response is a 500, you might want to check that out. Up to that, the experience was rather enjoyable and I was really looking forward to creating a FAQ page using your service.
