Many-to-Many is a wiki on Social Software by Sebastian Paquet and friends. The design and idea parallel what we are doing with a private wiki on TAPoR.
What can we learn from it?
Here is what I like about it:
1. Search in upper left.
2. Clean design
3. Introductory tour
4. Recently viewed
5. Screen Layout preferences
6. Links are not run together words like TryThis
7. Easy to read
8. Open
I read about this thanks to Seb’s Open Research.
