These are some notes on a Twitter-like microblogging service built on top of RemoteStorage . Besides duplicating Twitter functionality on a distributed platform, this also allows the control and ownership of content that RemoteStorage applications provide.
After initial setup the app polls all the /public/status directories of all the people in the “following” list (perhaps within a certain timeframe) and merges them into a timeline for display purposes.
Mentions could work just like Twitter by mentioning the full RS (webfinger?) name of someone (ie firstname.lastname@example.org).
Discovery of other users is a bit trickier (following requires knowledge of other users public address). This may not necessarily be an issue though since intrinsic discovery mechanisms (especially the semi-forced kind) are one of the downsides of Twitter as far as I’m concerned.
