I'd have addressed this in the article, but it was getting too long already. Short answer is that many of the best opportunities I've received have arisen as results of relationships formed on the Internet, first, and maybe over a few beers at a conference.
Cultivate relationships in whatever form they take.
Thanks for the reply. I was asking because a study done by 'Freelance confidential' asked Freelancers "Where do you find work?" "Referrals" scored 39%. Portfolio website scored 19%. Didn't think about it but I suppose referrals via the web work just as well. 71% of all freelancers complete most of their work at home btw.
