I guess just about anybody who blogs, or even routinely reads blogs, is also aware of Wiki. If that's you, then skip this entry.

To the rest of you (if anyone)... Wiki is the name for a collaborative internet project that allows multiple users to add to or redact web content. It's a powerful system. Witness Wikipedia.org Here, in less than three years, users from all over the world have compiled a free encyclopedia in several languages - without the help of paid staff-writers. It's all volunteer. More impressive is that most articles are far more up-to-date than encyclopedia articles from any other source. If the there is a revolution in Haiti tomorrow, it will be a part of the Wikipedia article on Haiti tomorrow night.

Most impressive is that the system is self-policing. If I edit the "up" entry and change so that it talks all about "down", someone else will have it changed back in a flash. So anyone can make edits, without fear of the system being degraded by vandals. Check out their entry on Weblogs. And while you're at it, give a thought to the hybrid Bliki.
