why the early adopters of Bitcoin and then active members of Bitcointalk have gone inactive now
Many reasons, but one is old as
time the internet:
Eternal September or the September that never ended is Usenet slang for a period beginning in September 1993, the month that Internet service provider America Online began offering Usenet access to its many users, overwhelming the existing culture for online forums. The influx in Usenet users was also indirectly caused by the aggressive direct mailing campaign by AOL Chief Marketing Officer Jan Brandt in order to beat out CompuServe and Prodigy, which most notably involved distributing millions of floppy disks and CD-ROMs with free trials of AOL.
Before then, Usenet was largely restricted to colleges and universities. Every September, a large number of incoming freshmen would acquire access to Usenet for the first time, taking time to become accustomed to Usenet's standards of conduct and "netiquette". After a month or so, these new users would either learn to comply with the networks' social norms or tire of using the service.
Whereas the regular September freshman influx would quickly settle down, the influx of new users from AOL did not end, and Usenet's existing culture did not have the capacity to integrate the sheer number of new users following September 1993. Since then, the popularity of the Internet has brought on a constant stream of new users and thus, from the point of view of the pre-1993 Usenet users, the influx of new users in September 1993 never ended.
