I have been one of the beta-testers for Stiki. Tobi has done a great job and listened to the feedback. Now I can say, that finally there's a smart way to have a great wiki tool and not pay fortune for Confluence and all the features you may never need.
As a creative director of a mid-big team I really need to say, that Stiki makes a great tool for me tracking the whole process of the creative thinking my team and I are involved in almost every day. Ideas don't get lost and can be easily reworked or improved. Anytime, everywhere and by everyone.
Beta user here. Jumped early onto it because I realised that all my notes and company details are shattered in my inbox, evernote, trello and others. Stared really documenting my internal processes to get VAs to take over several tasks.
