Your premise needs to be more specific. Such as, "like Linkedin, Blogger, Wordpress, Hosting service, App Engine, Amazon services, Github, etc." or "focused on mobile/desktop (app dev/test/product design)". I'd say if you're a freelancer knowing your specialty and not trying to be so broad based is a good idea, as you're essentially a one man show and no time to do everything from scratch. Looking forward to the answers..
