This site is the original Wiki. After I retired from Microsoft, I posted this link to Wiki's and the development of SharePoint. Now, we have come full circle, where Google's new Wiki project is claiming to be a "Sharepoint Killer".

The "Team Collaboration" category will continue to have many variations and spin-offs. I find it interesting that, on the internet, we have a very rich ecology of competing products across many categories. Compare to the relatively stagnant competition for desktop application software, where 90%+ of the market is held by the category leaders.

It may come to pass on the Internet eventually as well, but with the barriers to entry so slow, the competitive landscape may remain quite rich.

Quoted: SharePoint is, in some ways, a descendant of WikiWikiWeb. I think it was in 1995 (maybe 96), that I found WikiWikiWeb and was fascinated by the potential to have a Web-editing interface using a Web browser. I created a simple CGI program of my own, which I called QuickWeb. I was the Microsoft Outlook development manager at the time, and I created a QuickWeb Web site internally, that we could use in the development group. We ended up using it for status information, updating info about the current day's build, etc.
...
When I was ready to move on from the Outlook team, I set off to create something more extensive, as an extension of the QuickWeb idea. I wanted to incorporate something with a richer data model; something with a real database behind it rather than as a collection of flat Web pages. I worked on my own for a couple of months, creating a prototype of what I called "TeamPages?".
...
In order to make this a real Microsoft Product, I focused on integration with both Front Page and other Office applications, realizing that in order to be a success, TeamPages? would have to be a great way for teams to share their Office documents, as well as be an add-on to the standard Front Page Web editing tools.
...
Eventually, my small team merged with the Front Page and OfficeWebServer? teams, and we became the SharePoint Team Services team. Our first product shipped with Office XP. Internally, at Microsoft, SharePoint has become a huge success. There are many thousands of internal team and project Web sites that have been created with SharePoint. It has all but entirely replaced the dumb File Share, as the de facto center of group collaboration.

Yeah! I hope it's worth the wait! It looks like Google took the time to thoughtfully figure out the integration points with their other online document creation tools.

Google is thinking of this as a SharePoint "killer". That's interesting that the team collaboration scenario is central in their minds about how these wiki's will be used. This is a major competitor to WetPaint and BaseCamp as well (not to mention all the other hosted wiki tools, e.g. PBWiki

What is being done with Google Pages, now. And what about integration with Google Groups (which have yet ANOTHER wiki-like editing tool alongside their mailing lists).

In an interview today, Google’s Management Director of Enterprise Matthew Glotzbach called the combined products under Google Apps a “Microsoft Sharepoint killer” because it’s allowing businesses to collaborate without all that expensive Microsoft software.
