Mini freelance projects

WooThemes recently announced a partnership with Codeable for referring people for small customizations to their sites. Now Envato announced Microlancer for a similar concept. I know there are others, like Tweaky, as well. And there’s a WordPress centric one somewhere too I can’t recall. Seems like mini-freelance projects are quite the trend.

I know a ton of personal contacts I get are basically for this type of service. What do you think? Is it sustainable for a freelancer to work this way? I don’t (typically) find it terribly profitable or rewarding. But it can be consistent.
