I think I understood the word 'twitter'.

When you have time, a quick explanation of what this will do and why I might want it in words comprehensible to a bear of very little brain would be gratefully received.

I'm a user of twitter (among other things, I try to greet every single person who announces a new #n900!) so anything to make twitter easier is good for me. I currrently use Witter, and am very grateful to Daniel for it.
