Well, i have been using some networks since 2 years now. And the number of available networks is increasing too fast (viadeo, linkedin, xing (openbc, hi yann ;)), ryze, facebook, twitter, pownce, digg, del.icio.us, mahalo, seesmic (hi loic ;)), youtube (hi skal ;)), joost, dailymotion (hi nathan, sony, yann, stephane, carlos ;)), myspace, emurse, plaxo pulse, ziki, hulu, google reader, ...),
I'm a regular user of linkedIn, Facebook, Twitter, mahalo and expecting good things in 2008 on Joost and seesmic. it's time for a common api for all of them, it's so boring to build a new network on any new website or to invite/import the same people everywhere. When will this stop ? it's now time for the opensocial api with the granular privacy control like on facebook.
Please google make this dream come true in 2008 ! Happy new year.
