Dion Hinchcliff has been receiving some much-deserved kudos for his year-end lists of the best Web 2.0 software. I'm happy to   report that the second part of Dion's list features some Canadian content - gotta wave the flag, don't ya know - with 2ndSite recognized in the best online business software category. To be told, I'm friends with the guys who run 2ndSite but there's no doubt in my mind the Toronto-based company online invoicing software is the real deal for people/companies looking for a more efficient and product way to operate their companies. Amid all the hype surrounding Web 2.0, 2ndSite is a business with customers and revenue.
