Socialtext Releases First Commercial Open Source Wiki Socialtext Enterprise Wiki "Socialtext, the first Wiki company, releases Socialtext Open at the O'Reilly Open Source Convention (OSCON). Available for immediate download, Socialtext Open is the first open source wiki with a commercial venture as its primary contributor. Over 2,000 businesses run Socialtext Wiki products today as a hosted service or appliance."
Socialtext is a fascinating company. In many respects it's an independent software vendor (ISV) that refuses to play by established rules. It offers a hosted service, an appliance-based alternative (which essentially means a hosted service running behind an organization's firewall), and now a free, open source version, but it doesn't sell software products per se.
Socialtext CEO Ross Mayfield told me he anticipates a sufficiently large percentage of people who benefit from the Socialtext service/software will opt to pay for it (as a service and/or appliance), and I think he has placed a smart strategic bet.
In any case, it's great to see Socialtext continue to accelerate wiki evolution and mainstream adoption.
