Following on from the launch of two very successful projects (WIX and WTL) on SourceForge.Net, Microsoft has now launched its third open source project, FlexWiki.  I'm not even going to get into the potential for hidden agendas and other ramifications of this most recent OSS venture, other then to say…interesting…VEERRRYYY INTERESTING.

Microsoft's three projects allow developers to build collaborative online content, build installation packages for Windows products and create graphic interfaces for Windows programs. The Windows Installer XML software, posted on SourceForge.net in April, has received over 100,000 downloads while the Windows Template Library, in its fifth month on the site, has received over 23,000 downloads — placing both projects in the top 10% of active projects on the site.
