Knowners is a WordPress plugin developed by FakePress and Art is Open Source to setup an effective link publishing website.
The plugin is still in beta, but it already offers interesting possibilities.
It is thought as a large scale widget, usable inside your WordPress websites to setup a link sharing area on your web page.
You can publish links, categorize them with tags, automatically create relationships and taxonomies.
This plugin is in its 1.0 version. It still has limited functionality. We are working on it. We would love to hear from you, with your suggestions on the features you would like to have.
Please check back soon for updates: we are releasing a new version in just a bit, with an enhanced link editing scheme (the current one is quite limited).
