It's been nearly 2 years since I joined Yahoo! and the the semantic web-based technology I helped develop has been deployed in production for some time. It has been encouraging to see the ideas get more accepted since today I noticed that in a hotjobs search for rdf yahoo near Sunnyvale there 5 jobs open - not in my group, but in Yahoo! Local.
Our group in Sunnyvale is continuing to look for HTTP and web caching experts, designers and coders for building REST-based web services. Right here and now we have interesting, large scale, rich data problems and are applying semweb techniques to them. Contact me if any of this sounds exciting to you.
