I didn't know there were a whole lot of jobs out there on Twitter, till I bumped into this site, thanks to one of my fellow Tweeter.
One of the tweets you can follow is right here -- freelance jobs on Twitter!
There is yet another site, which lists 50 people on Twitter that job seekers should follow!
Then, there is also the Freelance Supermarket!
Right then folks! Here are three links that you may find useful. I haven't tried any so far, and therefore, look forward to your feedback.
Good luck with your search for freelance jobs!
