Less risk => more ideas in an organization?

I'm exploring an idea for letting everyone in an organization discuss ideas, opinions, questions, and answers on an equal basis.

• Anonymity will reduce both reputation risk and personal bias in reactions/responses—so both new people and "the boss" can participate equally.
• A consistent scoring scheme based on reactions/responses identifies popular/resonant items.
• Authors can publicly claim their posts if/when they want, while remaining unassociated with their unpopular ones.

For example:

• Float risky-feeling ideas to see if others think they might work
• Collect answers and see which are more accepted/supported
• Post things you don't agree with to see if others reject them, too
• See if you tend to agree or disagree with others around you

Would you share more ideas/problems/suggestions/questions in your organization with this kind of thing in place?

Thanks!
