If your applications have to do with content (and they do – read on), you shouldn’t miss TSS’s video interview of David Nuescheler, the JSR-170 and JSR 283 spec lead.
David explains his everything is content mantra, and the more I work with this technology, the more I agree.
We’ve been working on a dead simple javascript-based interface to JSR-170 lately, that will make content repositories much easier to access. Stay tuned!
And by the way, David is also CTO of a cool company that I’m kinda related with. We are looking for talented people, see you there maybe?

AFAIK they are guys that left Day. Day is not particularly happy with them :-)
Cooler? Well, I guess everyone’s allowed to have their own opinion on this ;-)
