We're wondering if there's room for something light & inspiring, like github and posterous are for their respective tasks. We've found one key driver to a successful collaboration experience is how effectively it integrates into your workflow, which for us means email. Few tools seem to do this well without being heavyweight.

Most people we've talked to are passionate one way or another, and we've enjoyed the discussion. Some of the questions we've asked are:

1. What type of projects have you used wikis/shared documents for? How many readers and writers were involved?

2. Think of a specific project where a wiki or <insert your tool(s)> was invaluable. What made it work?

3. What didn't work? Was it an issue with the collaboration process, tool or ... ??

4. What was the typical workflow like for you? What were the pain points? How would you have done it differently?

5. What is the minimum set of features that would be required to be useful?

Tell us your thoughts. We would be happy to clean up & publish the results if it would be helpful for others (we'll do this if there are sufficient responses to warrant this, say, 50)
