Building on the success of its two last iterations the Web 2.0 Expo is back again, this year featuring a much-enlarged program. If you've never heard about this major event, the Web 2.0 Expo is a "global annual gathering of technical, design, marketing, and business professionals who are building the next generation web", as they put it themselves. Worldwide interest in emergent media and communications being at its peak, I'd say this year's edition should feature record attendance, so better book your tickets quickly.

This year's program features four main conversational themes: education, networking, startups and a tradeshow presenting the latest tools and technologies available. The event will feature a host of keynotes, workshops and conferences covering different aspects of these themes, in addition to the expo hall itself. For those of you who can't attend physically the Web2Open "unconference" might be a semi-satisfying option, as some of the on-site conferences will be "hybrid" and allow online users to participate in the discussion. My two cents is they might throw in some webinars as well.

 Web 2.0 Expo will be held at the Moscone Center in SF from March 31st 'til April 3rd. Check out their blog here. You may also join the W2E Facebook Fanpage, or follow its tweets by adding @w2e to your list.
