You're being disingenuous, or intentionally obtuse.
Intentionally obtuse. The only difference between putting my rant on a server I host and a server Facebook hosts is that I don't have to deal with someone else' system and ToS and such. It doesn't make one scrap of practical difference in the world if my url is www.thisiswhereirant.com or www.facebook.com/thisiswhereirant. Well OK, one difference. FB gives me a little bit of exposure that I wouldn't have on my own site (via friend-of-friend linking.)
That more of a consequence of the inability of the journalists to classify it
What? I'm pretty sure someone could have come up with "impermanent social media" if the permanence aspect was something anyone cared about in relation to the term "social media." But they don't.
I'm starting to wonder if you're interpreting "social" as in "socialism" rather than as in "socializing." That would explain a lot. Most people (myself included) think about the latter when they discuss "social media" though.
I think I pretty much want to out Bob as a Nazi everywhere.
Ok so your next post is "Bob's a Nazi jerk so I defriended him and you all should too!" Right after defriending him. Wow. That was hard.
If you want to take on a dedicated mission against Bob well then you're welcome to do that, but that's going well beyond the scope of social media and into the realm of maybe you being a bit crazy as well.
Younger users accept *all* friend requests. If it turns out they don't like what the person is saying or doing, they "unfriend" them later.
And that invalidates my argument exactly how? At the end of the day, the jerk is still not a friend (in either the real life or social media sense of the term.)
I think you haven't been following the whole GamerGate sock puppet situation very closely.
Again, that's relevant exactly how? Just because an ingrained problem happened to be exposed via a particular medium doesn't mean its intrinsically tied to that medium. Sexism was alive and well in gamer culture long before anybody made the first terrible post.
Once you are inside the web of trust, you're inside, and even if someone wants to not hear from you
That's what defriend and ignore are for. Bob might still be in my friend-of-friend "web" and perhaps you'll still see the things I post on their wall (or equivalent) but I don't have to see any of Bob's rants myself. If my (remaining) friends want to continue seeing Bob then that's up to them.
This is, in fact, precisely how the TOR network had been infiltrated by various third parties: peer-of-peer implied trust relationships.
Again, not sure what this has to do with anything. The fact that the TOR design turned out to have flaws doesn't mean they can't be corrected.
It also has little bearing on a decentralized social network unless that network piggybacks on the TOR protocol or intentionally makes the same mistakes TOR did.
Finally keep in mind that while the profile itself would need to rely on a computer-to-computer web of trust, what you as a person actually see would be based on your friends list and associated preferences. Bob's profile may well be stored on your computer as part of the protocol but that doesn't mean it ever has to be visible to you. Once you defriend him it just becomes another anonymous profile that you're only storing for the sake of decentralization.
