I admit it, I'm on Twitter. I have been for a little over a year. I have a fairly low opinion of it in general, but I am still on it and make random comments to people from time to time.
Earlier today, one of the people I follow tweeted that his young (under 5, I believe) daughter had just done something stupid. Nothing illegal or immoral, just the sort of embarrassing and sometimes destructive stupidity that young children tend to get into. And he then tweeted it.
Which means that his under age daughter's actions are now part of the permanent archive of the US government.
