The following is an extract from a blog run by Michelle MacPhearson - super entrepreneur in the social media marketing area. This entry concerns outsourcing and describes how one service works. It's a great commentary on how things are changing.... (this posting does not represent an endorsement or otherwise - have not used the service yet).

"Odesk

Odesk is a marketplace where people from all over the world list their skills and resumes and folks like you can hire them. You’ll can negotiate pay, search contractors, list jobs you have available, etc. Good for both short term and long term work.

What I really like about Odesk is that they ask all contractors to install a little piece of software on their coputers that takes screenshots of what they’re doing at random intervals. You then get access to those screenshots. You can quickly see if they’re actually working on your project, and you can see that they’re doing it correctly. I’ve found Odesk workers to be pleasant and motivated, and I think the screenshots that are taken keep them on task. Odesk folks have consistently performed tasks very quickly. It’s the first place I stop when I need a new contractor, and I think you’ll enjoy the service as much as I do."
