Thursday, 31 May, is Google Developer Day. Lots of events streamed online. A great way to learn about their web APIs, mashups, client APIs, AJAX, XML, commerce and all the other shiny buzzwords. No voice, IM, or email sessions.

Ten countries, one very long day, thousands of developers, free to programmers. The California event is too big for Google's Mountain View campus, so they moved it to the enormous San Jose convention center. 

Developer relations writ large.

If I can crash the event I'll bring back some details, but track the GDD07 tag on Picasa, Flickr, Photobucket and see related posts on Google Blog Search and Technorati.   

Same time, next door at the San Jose Marriott, is the Inbox conference. Several sessions on unifying IM, email and voice messaging. Case Study: Designing an Email System as a Back-end for Voicemail. The Power of Presence. Enterprise 2.0 and the 'Resocialization of IT'.
