I stumbled upon this post about 5 Steps to Jumpstart Your Website [or blog] over at College Startup.
I took the author’s advice and posted Top-Level Domain Survey (or what to do when your .com is taken) to his number one recommendation and got about 30 hits in 30 minutes from the source. Not bad for 2 minutes of work. (Not including the hour or so I put into creating the survey and blogging about it.)
YMMV depending on your audience, post and title.
