Frederico, www.riapt.org is an open community. Everyone can post on the blog. More important than the blog, is the Mailing List. We have a ML with 123 members. The interest in Portugal is still small, but it's growing fast. I think you should try joining the ML. :) We are also promoting some events, and making efforts to bring Adobe speakers to Portugal, probably on February. Stay tuned.
