Perhaps the best introduction to Syndie can be found in Syndie itself.

Updates can be found by filtering for the syndie.intro tag (if you only want to receive posts that jrandom made with that tag, that can be achieved as well).

If you have any questions or problems with Syndie, just post them and syndicate it up to syndiemedia.i2p (which should show up as the default archive on new installs). You can also use the I2P forums if you're having trouble getting Syndie to work, and people are almost always around on the #i2p irc channel.

One FAQ which might keep people from getting more posts into their Syndie node regards cookies. If you get "internal errors" when using the syndicate form, you probably have cookies disabled. Syndie needs cookies to help maintain state, and while its good practice to disable cookies in general, you should be able to tell your web browser to make an exception and allow cookies to "localhost" (or wherever your Syndie instance is).
