I thought I'd let you all know about Google I/O, a developer event upcoming on the 28th and 29th of May at Moscone West in San Francisco. There are a lot of exciting opportunities at the event, including: breakout sessions, code labs, fireside chats, tech talks, and sessions that you, the developers, can hold yourselves.
The talks will cover a variety of topics, many of which focus on gadget-related technology. Be sure not to miss "Apache Shindig: Make Your Social Site an OpenSocial Container" and the related code lab. The two discussions will focus on deploying OpenSocial applications, but Shindig can be used to serve gadgets on your site, social or not.
