I have many reasons to dislike Fb but at the top of that is how gated it makes communities.
If Facebook is such a problem then people could just stop being part of these social circles. It really isn't that difficult.
Will you only decide which hobbies I may have, or do I have to submit planned meals and TV watching for your approval, as well?
"Just stop being part", my ass...
No, it actually is that difficult, or more precisely that undesirable. Very few people are such anti-Facebook activists that they're going to dump valued friends and acquaintances in order to dump Facebook. That's why Facebook is going to hold on to a lot of users, and why it'll end in a whimper and not a bang.
The only case where it "really isn't that difficult" is if you have no valued relationships that have a Facebook component.
Not necessarily. Lots of social circles use Facebook Events to organize get togethers, and not having an active Facebook account leads to you being left out. The people leaving you out may only be acquaintances, but that doesn't mean it's ok.
This is the reason why I still have a Facebook account. It's obviously and explicitly inactive, and I only log in when I get an event invite.
