People are suggesting that we should go to another web site, or form one, to get out of the Slashdot Beta trap, but I will put forth a suggestion - this could be an opportunity to rejuvenate Usenet, to post in the manifold moribund groups, and to create a renaissance of uncensored Internet joy such as was common in the old days. No longer should we merely enrich some soulless company just to have a handy discussion forum.
Usenet presents many advantages. It is not controlled by any one entity, it works well for low-bandwidth users, one can completely shit-can abusive posters, popular topics are promoted by replies and not by peevish moderators, and it allows discussions that can last many months or years.
I know that many ISPs no longer provide Usenet feeds, but if you search for Eternal September you will find a very nice, free (donations accepted) Usenet provider, the only caveat being that binaries are not allowed. I use it and I suggest you all do to.
