Random Catch-ups: Semapedia and SWiK

Neither of these is new, but I've not mentioned them before, and I should have done.

Semapedia:

Semapedia.org is a non-profit, community-driven project founded September 2005. Our goal is to connect the virtual and physical world by bringing the right information from the internet to the relevant place in physical space.

...

To accomplish this, we invite you to create and distribute Semapedia-Tags which are in fact cellphone-readable physical hyperlinks to the free online encyclopedia Wikipedia (or any of Wikipedias' sisterprojects such as Wikibooks, Wikinews, and Wikiquote). You can create such Tags easily yourself by choosing and pasting a Wikipedia URL into our creation-form. Pressing the button will generate a custom PDF file to download and be printed. Once created, you put the Tags up at their according physical location. Others can now use their cellphone to 'click' your Tag and access the information you provided them.

SWiK:

*SWiK.net is a project to help people collaboratively document open-source software*

SWiK is visited by over 10,000 people daily, it’s a place to make notes and publish articles on software development and open source projects, tag projects to help organize the world of open source, or just browse around and find interesting stuff.

I particularly like the Zeitgeist page as a snapshot of what's hot.
