This is the answer to Moots vs. Waves. How do Google Wave and Yoomoot compare?

Google Wave only works for small groups; Yoomoot works for groups of any size

Imagine everybody could see everyone else's 'waves'? The result would be an utterly overwhelming mess. Wave is principally designed as an email replacement, so it's focused on private collaboration between small groups of people.

yoomoot meanwhile works for both small groups and immense groups.
