We have just launched http://planet.wikimedia.org/ , which is an aggregator for all on-topic wiki-related weblog (blog) posts by participants in Wikimedia projects. The planet can be found at:

http://planet.wikimedia.org/

To get added, please follow the instructions at:

http://meta.wikimedia.org/wiki/Planet_Wikimedia

This is a kind of beta test, and right now, the planet is in the English language; however, I have prepared a process for requesting new languages to be set up here:

http://meta.wikimedia.org/wiki/Planet_Wikimedia/New_language

So please add your support if you wish to aggregate blog posts in another language.

Again, this is for on-topic posts, not for diary entries. All feeds must either point to a blog which is almost exclusively about wikis, or filtered (WordPress, Blogger and other common blog engines all support filtered feeds by categorizing your posts, e.g., adding the "wiki" category to all posts which you want to be included in the planet). If this makes you feel uncomfortable, you can (in addition or in substitution) add your blog to http://wikiblogplanet.com/ , which does not filter posts for on-topicness. WikiBlogPlanet is run independently by Nick Jenkins.

I hope that this new tool will allow us to share useful and interesting information, as well as opinions, more effectively across project boundaries.
