Great find. Being a freelancer is not an easy task. Many would love the benefits, but looking for work unless you are already popular and established can be a great hurdle. I think Lancerlist would actually help freelancers more than those who hire them. 

There are many countries in the list. But USA seem to get the mostf ocus. It would be wise to market ting more towards markets like India where internet is booming and where there is a lot less competition but a vast amount of people who could be looking for work.
