Hi again Khürt, a couple comments about your experiments with Keyring:

Keyring (and the importers) are definitely tested up to the latest WordPress version. I actually run both on my site, which runs the trunk of WordPress, so I tend to find out pretty quickly if things break.
What are/how do "Syndication links" work? Or how were you expecting them to work? The Importers all store a fair amount of metadata for each thing imported, along with the raw data from the API where it came from. We should be able to get that fixed pretty easily.
RE: the formatting of the post -- that's largely up to the theme that you're using, which is part of what makes developing plugins like these so complicated for WordPress. I ended up deciding the put the comment in the title and the content to try to handle all situations, but at some point I'd like to ship the importers with some concept of a lightweight templating system of their own, or some other way of making it easier for the site owner to define how they'd like to import the different pieces of information available.

Cheers.
