10 Sites and Services That Will Matter in 2010

A year ago, I chose ten sites and services to watch in 2009. Of those ten--TV.com, Qik, Boxee, Loopt, Blip.fm, Power.com, Tweetag, Hi5, Tripit, and BlackBerry AppWorld--only Boxee and (to a lesser extent) Blip.fm became well-known names in the past 12 months. According to Web-analytics company Alexia, though, Tripit and Qik saw significant growth in 2009, and Qik's time in the sun may still be coming. Truth is, the past 12 months were a tough time for any new site or service to find its legs--just staying alive was doing pretty good.
