Re: FriendFace! FriendFace! FriendFace!
"1. Once people have entrenched themselves in a set up with all their mates, the whole party has to move else no one will.
Or...
2. Wait for the next "generation" to decide against established social network and pick a new one.
Or...
3. You couldn't careless about any of this social networking bollocks and simply want a bloody good laugh at all the muppets and their so called online "friends"!"
I see quite a bit of Facebook-fatigue, but that's more with FB playing games with what comes up on your feed than the ads. The Ads aren't very noticeable if you're competent at using a browser (as in installing adblock) so I don't think most people care. I see a lot of people abandoning it for twitter since it's a lot more low-key.
As for #3, I've been out with my friends way more since FB than before, it's a lot easier to coordinate than via phone or text. Maybe if all your friends go to the same pub every night it's easier to skip it.
