I hope that Yaron doesn't mind me taking a second to announce
Wikifeeds, a site that uses Semantic Mediawiki and Semantic Forms.
You can access this site at http://www.wikifeeds.com
Wikifeeds is a project that aims to create pages populated with
relevant web feeds that are updated every hour. This project is
similar to sites like popurls® and Alltop with the difference being
that pages can be created and updated by anyone in the world since it
is a wiki.
An example of a page that has a decent amount of content can be found
here (apologies to any fans of USC, Michigan, etc in advance):
Edit (using Semantic Forms):
Also, I wanted to thank Yaron for helping me through some pitfalls in
getting this launched. Much appreciated!
