Has anyone here tried oDesk?

oDesk is kind of like RentACoder, except it's designed around hiring people hourly instead of by project. This can be a lot easier for me, at times.

It also has an advantage over RentACoder in that a lot more data about each person is available and searchable.

It seems like this could be a good place to find people with some very specific skill sets.

What do you think?
