One of the new developerWorks Spaces is on SOA.
I've talked about developerWorks Spaces in general. One of the community topics that I'm particularly interested in is SOA development and best practices. It lists the latest SOA-related stuff: articles, podcasts, events, briefings, etc. Makes it much easier to figure out what's new on dW concerning SOA.
One thing I'm not clear on is how this is going to differ from the dW SOA and Web services zone home page; the spaces page appears to be part of the zone. I guess the zone page will focus on what's in the zone, whereas the spaces page will pick stuff from all the zones and other parts of the IBM web site, and maybe even related sites.
In any event, check it out, it's a good place to find our SOA materials.
