Purchased it since the free domain was conveniently "suspended". They said it was against TOS when it got a couple thousand hits, I said WTF, explain! They unsuspended it when it went back down to regular traffic. Funny how .tk placed ads all over the "suspended" page when thousands were hitting it a day, then gave it back when it dipped under 100.
Anywho, figured a TLD is more professional and will get better search results/not be blacklisted then a free domain.
