So there is a new twitter-like social network called mastodon that works off of distributed federated servers. It looks like it should be able to work nicely with xmlhttprequests which means that it could work well with twederation. I need to look into oAuth to see if we can make posts as well as get them.
Either way I am very excited about mastodon. You can sign up over at mastodon.social, my handle there is @inmysocks
