Apologies if this feature request is too far out or has been discussed previously.
It'd be cool to see a live feed / content stream based on, say, twitter posts of all users who have listed an associated twitter account.
For a simplest possible concrete example:
Add a top level page called 'Talk'. When users click that (or navigate to, say, /talk), they'd see a live feed of all tweets from users on the site.
It'd also be cool to display everyone's github status updates ("@joeperson committed code to Calegator"), and maybe even visualize connections within the community based on twitter or github links, but that's another thing altogether.
Thanks,
