What the heck is twitter?

Apparently there’s this new thing called Twitter gone and showed up while I was out drifting the ocean waves.

What the heck is it?

Just WHY is it popular?

What is the point, pray?

Why do posts look so UGLY with it?

Is there any reason to use it, and how can it be used usefully?

Half the media seem obsessed with it, the other half seem scornfully scathing of it…
