I used it last summer to find a babysitter for my kids for my sister's wedding. I really liked it. They do a background check on the people and you can get references. I put out an ad and had several responses. I would use them again. We just can't really afford to pay a sitter at the moment =)
BTW, just in case you didn't know, you do have to pay to use it... you can look around without paying, but you can't communicate and you don't have access to the background checks and such. I went back after my subscription expired to see if I could find the number to the sitter we used last year and they took all her contact info out of our messages that we had sent back and forth.
