I've designed over 4,000 logos and who knows how many other items (business cards, etc.) in the past few years, as the owner/designer at The Logo-Mat. These 4,000+ projects have stemmed from various leads such as word of mouth, Twitter, Facebook and Craigslist. I have never once been setup or offered a project from LinkedIn.
I've had an account for years, participate in posting daily, have plenty of connections, recommendations, etc., but why can't I score a gig? Isn't that what it's for- meeting professionals? WTF are people doing on there? I have to admit that their interface has improved in the last year, but I still don't get it. Why am I "LinkedOut"?
