I am a registered user in ServerFault, SuperUser and several other sites, only because I had to ask 1 or 2 questions. In general, I have no interests in these sites, so I don't want to see them on my Feed. Is it possible to hide them somehow?
For now, I want to see only 4 sites (could be meta or non-meta) on my Feed. Notifications are not an issue, because I normally don't get any notifications from those not-interested-in-sites; I rarely participate there.
