There should just be a simple checkbox in twitter for “Are words violence?” The people who say “yes” only see tweets from people who agree.
Two things I’m not clear about are: whether it’s twitter or Twitter (I say Twitter); and whether it’s tweet or Tweet (I say tweet).
My attitude to Twitter is that for as long as it exists, I will occasionally cherry pick it, and thus adorn the blogosphere. Twitter is very temporary, and will soon collapse, I think. A small group of people has the power to collapse it. Eventually they will. The blogosphere is dispersed in its management, and will endure as long as our civilisation does.
This blog may even endure for quite a while. Even my old blog endures, for the time being, and even though it doesn’t now work properly.
