I stumbled into a lucky situation maybe 5 years ago. I posted a topic on a development forum mentioning my services and linking to a couple of examples. I received a few responses, people wanting work done for a couple hundred dollars, which would basically be a waste of time. Anyway, I get caught up with other projects, and a few months down the road someone sends me a message on AIM, saying they saw my post, and needed a quick project done in the next couple of days. Turns out they're a huge firm in New York with a bunch of Fortune 100 clients. Why on earth they sent me an instant message on some half-assed forum post, I'll never know. I ended up working for them for years and 80% of my work originated from them. It launched my career, and I quickly went from being a freelancer picking up scraps to working on big name projects and networking with tons of great people. All thanks to a random forum post, one of the few I ever posted during that time.
