Two great free hosted wiki services
Schtuff and Writeboard provide good wiki functionality for free
The wiki market is maturing nicely with the arrival of some excellent hosted wiki services which are totally free within average levels of usage. Two of these free wikis which caught my attention are Schtuff from JanRain Inc and Writeboard from 37 signals.
schtuff is is a classic wiki which allows you to create a number of independent hosted spaces within it. You can invite any number of other users into each space with permissions ranging from admin to read only.
Each wiki page maintains a full history of versions with ability to revert to a previous version and to compare two versions. You can subscribe to spaces or even documents within spaces and you are notified by email and/or RSS if they are changed.
You get 3 spaces and 200MB for free and the developers say that they partly cover their costs via google ads within each space and will soon offer a paid subscription for users who need additional spaces or disk (prices not yet available).
There are some minor useability issues, such as the current inability to re-invite users or add attachments in a single operation, which reflect the newness of the product but given its functionality Schtuff is a very good choice if you are looking for a comprehensive but free wiki.
Writeboard allows you to create any number of writeboards (i.e shared pages) and invite users to share them.
It lacks some of the functionality of Schtuff in terms of tags and indexing but I prefer the way it manages and shows the differences between two versions of a page.
Whiteboard can also be integrated with the 37signals backpackit product (see my earlier review under The virtual road warrior software checklist).
The Writeboard user interface is clean and intuitive and provides a very nice solution for ad-hoc document collaboration between two or more people.
Bioteams Books Reviews
The way a team decides to decide is one of the most important decisions it makes. In the excellent book, "Why Teams Don't Work" the authors, Harvey Robbins and Michael Finley, identify seven key decision-making methods for teams.
