Bloggers have noted that Google has just about every online collaboration service except a Wiki. Back in October 2006 this was noted by Alessandro Vernet in "What Google Didn't Do: A Wiki".

Seems like we don't have to wait much longer as we are now getting reports like "Google Wiki Lunaching Soon?". Of course we know that Google has acquired JotSpot, a wiki service, so it is only a matter of time before we will see a Google Wiki it would seem.

So why would Google offer a wiki service? A Wiki is a collaborative website which can be directly edited by anyone with access to it. It has been described as the "simplest online database that could possibly work".

Essentially a Wiki can be used for a number of reasons, including using a wiki for marketing. Web Worker Daily provides a list of "15 Productive Uses for a Wiki" - a must read to see how a wiki can be used.

With Google coming out with a wiki soon, it just makes it that much more reliable to use an online services such as Google's. You can trust that the wiki database will be available 24 x 7 just like Google Docs and Spreadsheets.
