Hi,
I think the last few years showed that what once may have been a reasonable point of view (i.e. trying to be a voice of dissent) is not possible on a site that actively prevents their users from seeing those dissenting views.
When will it be time to remove the FSFE page? Or is it the FSFE's contribution to make Facebook feel like a ghost town?
I don't believe that Facebook will ever feel like a ghost town as long as there is no exodus of a massive scale. And even then, the algorithms will do their best to give the last remaining users an illusion of an active social network.
When will it be time to remove the FSFE page?
Given Facebooks analytics capabilities I assume that this question does not need much guesswork. How many views does the site get? Are there any user interactions?
If the FSFE feels that the numbers don't justify the possibly tarnishing effect of being on Facebook, we can delete the account and get a nice press release out of it...
Cheers, Johannes
