Since Mindtouch launched their Deki Wiki software in July of 2006 they have seen nothing but steady growth, and that has now paid off in the form of 100,000 installations.
Mindtouch's wiki software has been seeing phenomenal growth of 50% a month, and the trend seems to be continuing upward. The company reports that the software is now being installed 500 times per day on various websites. Since the introduction of the platform last year, it has been translated in to four other languages (German, French, Portuguese, and Russian), which is always a sure fire way to spread your software further.
