Information

What is the best way to maintain information? Well that depends. If you want to share information and make it easy editable by anyone a wiki is the best. If you want to parse news a static html-page and rss-feeds are the best.

Wiki
The first Wiki, Portland Pattern Repository, has been made by Ward Cunningham on March 25, 1995. Although the Wiki idea is great is has also an important disadvantage: Vandalism and Spam Attacks. Vandalism can be stopped by using registration procedures to limit write access.
Also a Wiki will only work if the people want to participate. To some people a the Wiki self forms a barrier. To ohers it is just to much work. Or is it we don't want to share our knowledge?
I am currently trying Atlassian Confluence, an application combining Wiki, News and RSS. The first impressions are quite nice, but I have not opened it for anonymous use.
