+1 on communities/social tools for groups. I think one of the great challenges with the internet is that global broadcasting aspect of it. Knowing that something you say could spread across the world, and potentially hurt your prospects in the real world, is chilling and moderating. Our online identities/communication becomes more artificial in this environment. We feel the urge to broadcast what we think the world will think is acceptable/desirable, as opposed to what we truly think. I feel like increased privacy, more localized online communities, and increased ephemerality of our content could all help towards making the internet a better place. How to do that is obviously a huge challenge.
