When my cable ISP stopped providing Usenet access, it seemed that all the cable providers in the US dropped this service within several months of each other. At that time, a great number of Usenet posters completely disappeared, and most never reappeared.
I payed $11 a month for a Usenet provider for about 18 months afterwards, and then finally dropped my provider.
The cable and dsl providers unilaterally killed the Usenet, by not providing service, almost simultaneously. I know the Usenet is still alive, but only used by fraction of users compared to a few years ago. For me the Usenet in many ways was more useful than Facebook, twitter and other existing social networks of today's on-line system.
I would currently like a chromebook I2P client.
