After evaluating platforms for a key US client we only felt comfortable recommending one, TallyFox! Other solutions claimed that they enabled intelligent collaboration, but only one could actually deliver. Answers from others about "connected know how" and "folksonomies" were "that's an interesting idea" or "that's something you should talk to our technical team about." TallyFox met each need we have with "we do that" or "that is scheduled for..date". Our recommendation: ask the tough questions and you will come to the same conclusion we did; the answer is TallyFox!
