Humans pick each other's brain in a chaotic and unstructured way. Putting human communication on-line does not help much, as communicating via emails, social media, and forums scales badly and stays unstructured.
We propose Mindools (Doodle for ideas): a new way for a group to collect and rate contributions in a structured way. Our customers use Mindools for strategic reviews and virtual workshops but also polling and finding a common date. Our biggest Mindool have 100+ users.
