Liked How to improve Wikipedia citations with Hypothesis direct links (Jon Udell)
Wikipedia aims to be verifiable. Every statement of fact should be supported by a reliable source that the reader can check. Citations in Wikipedia typically refer to online documents accessible at URLs. But with the advent of standard web annotation we can do better. We can add citations to Wikipedia that refer precisely to statements that support Wikipedia articles.
Bookmarked Aggregator ― A WordPress Plugin (Kris Shaffer)
I've created a WordPress plugin called Aggregator, which will allow WordPress users ― bloggers, teachers, and students alike ― to collect their own annotations, annotations on a topic of interest, or annotations from/about a class, and present them in a page or post on the WordPress platform. It's easy to install, easy to use, and (I hope) will be of value to students, scholars, teachers, and writers.
This is an interesting approach to collecting comments and contributions from around the web.
