Two synching format RFCs
Dare Obasanjo posted an RFC for a synching format: Synchronization of Information Aggregators using Markup (SIAM).
The idea is to synchronize subscription lists and read/unread states of items.
Another format was proposed by James Huston: Syndication Interchange File Format (SIFF).
Yes, more acronyms!
But the idea is to come up with a standard format that can be supported by lots of different newsreaders.
