Adina Levin posts on the Socialtext Weblog about our support for Atom. Its less about the Atom syndication format than the API at this point (using a Kwiki plugin), and has really got me writing more in Etco (an offline editing client whose latest version simply rocks).
If the above means nothing to you, consider this: by supporting open standards, our product just got a whole lot better because of its ecosystem. Soon I'll be writing anywhere and publishing anywhere.
