Idea: Ideas Bank
Ideas would be categorised by subject area, theme, or incentive.
One could subscribe to the Ideas Bank by means of RSS feed or similar—nothing invasive like a mailing list.
Users e-mail addresses would be visible and/or available to allow for collaboration on ideas. I feel an in-built direct messaging service, like that of Twitter, would be detrimental—an e-mail would perhaps encourage a seriousness about tackling the ideas and would start a more personal connection between potential collaborators.
This is very similar to the imminent Medium which “is based on the belief that the sharing of ideas and experiences is what moves humanity forward” . However I feel their example page is too rich with stuff, I imagine a much more minimalist, simpler, less intimidating approach. Like that of Twitter, perhaps a limit of 140 characters, or similar, would make it more approachable, and less about the aesthetic of a users ‘profile’.
There would be complete parity among users, no hierarchy. So there will be no ‘following’ of particular users.
Abuse of the system would be self regulated, perhaps with a ‘flagging’ system—once a particular number of flags have been raised, the post is removed (?).
