Synopsis
Slashdot has a quite geeky use base, it might be supposed, that a lot of them would be willing to use a browser plugin to access Altslashdot, if the incentive would be save the community, disable ads etc. Still, a centralised webhosting would be needed, e.g. to attract novices or to support rare browsers.
The idea is, that if a lot of users use a bittorrent--style decentralised hosting, running the centralised web server would be cheap enough to life off donations.
