I agree with Mezzie about the good things about LJ, but one thing I think he/she is wrong about is that Twitter is "shouting into a void." In fact, even though your tweets may be set to public and any user can read them, your followers are your "circle" and most interactions come from there, not from random people.

The difference is that the access controls were built in to LJ and they're an afterthought on Twitter. The ability to finely control VIEWERSHIP (multiple different friends groups, for example) dampened a lot of things being shared without context.

Then again, screenshot culture wasn't really a big thing, yet. I don't think we could replicate some of what made LJ work anymore. It's sad.
