Yep, I'm a HitTail user. It's worked great for identifying easy to rank for longtail keywords that I can go after. I'm currently getting about 1,700 monthly uniques based off around 30 articles that were written to target HitTail suggestions. Not a huge amount of traffic but I'm very happy with the results considering what it cost me to have the articles written and that the traffic converts around the same as other organic traffic I'm getting.
