Last year has been the year of the Web 2.0. Myriad of startups in Silicon Valley and in the rest of the World - even in France ! that is an evidence of how it's easy to create a Web 2.0 thing those days ;-), tons of dollars from VCs and Business Angels... Google buying YouTube was * THE * news of the year, IMHO.
That is why I am proud to disclose my own Top-Ten List of Web 2.0 Stuff (i.e. companies, applications, websites, whatsoever branded '2.0'). Warning : it is a serious one, for I am convinced that all the companies - or the apps, more precisely - listed here can find their way into real business - for instance... in the Telecoms industry. I am beta-tester for some of them, intensive user for others. It's all fun.
ps : since we are talking Web 2.0, please simply click on each logo to see what's behind ;-)
ps #2 : to create the list, I simply dragged & dropped the buttons from web2logo.com into the Edit page of TypePad. No programming at all, just a pure simple quick drag&drop. That's the Web 2.0 Magic at its best !
