Great timing on this for me. I just posted a job (a real one) to Craigslist and received a handful of responses.

Making the assumption that I would get a bunch of resumes I decided to add one little hurdle. I asked the applicant to copy & paste their resume into the email body. I did this to see who was actually paying attention and who was just spamming every posting and hoping someone would bite. Sadly this hurdle come not be overcome by the majority of the people I heard from... The search continues.
