WordPress.org

This plugin aims to support community link-sharing, social bookmarking, and discussion of links in the WordPress environment.

This is still at an early stage of what I hope will be a much more ambitious project. If you want to try this out, please give me feedback.

I will guarantee backwards compatibility with all data saved by the plugin, so it should be safe to install and activate, and as I add features, your existing posts and links will work with them just fine.

See the plugin's wiki page on github for more up-to-date documentation (its hard to keep documentation updated in multiple places).
