Choice can be a cruel option. A few years ago an online professional profile meant Linkedin. Now due to the success of the latter we have loads of options. But do you go for one of the flasher new boys or stick with the increasingly spamy Linkedin? tough call, because most peps recruiting/booking gigs go to Linkedin as first port of call.
I have been trying out a couple of the new ones recently. Vizify looks great and is a doddle to set up. Maybe a bit too style over content, but I do like the look of it. Upmo is more Linkedin-a-like currently a bit buggy and some features are in 'coming soon' mode. It does feature a 'score' number, but a bit like Klout its debatable as to how valuable that may be.
