- Let your users control who they see and who sees them. This allows the user to limit their access and exert a level of privacy on your system. People hate (at least I do) being immediately available to other users on a social network if they can not control that contact in some way. This also allows users to control their exposure to spam!
- Allow users to notify one another of ones actions, Facebook beacon and Myspace action feeds do this, twitter does this implicitly on the site and through RSS feeds...this keeps the user in the social loop of their contacts and more importantly brings them back to the site to provide more eyeballs and keep ad impressions high.
- In a world of RSS feeds , email is still the most ubiquitous way to notify users of events on th site so allowing users to control email notification possibly in addition to feeds for appropriate content or features allows even more stickiness to extend to devices that otherwise aren't able to access RSS feeds, like many wireless devices.
- Community, this is the general goal, easily stated but difficult to achieve...the social interactions have to foster community between interacting users or give the impression that the users are part of a community. A portal where free interaction between users is encouraged allows this, giving users the ability to make new contacts and have more incentive to stay around. Allowing users to follow memes in real time fosters community interactions that keep the community vibrant.
This will surely go down as a seminal advance in cancer therapy. It reads like magic:
So this new approach looks for the specific proteins that are associated with a given tumors resistance to attack by the body's T cells, it then adjusts those T cells to be hyper sensitive to the specific oncogenic proteins targeted. These cells become essentially The Terminator T cells in the specific tumor AND have the multiplied effect of traveling along the immune pathway of spreading that the cancer many have metastasized. This is huge squared because it means you can essentially use targeting one tumor to identify and eliminate distal tumors that you many not even realize exist.
This allows the therapy for treating cancer to, for the first time; end the "wack a mole" problem that has frustrated traditional shot gun methods of treatment involving radiation and chemotherapy ...which by their nature unfortunately damage parts of the body that are not cancer laden but …
