Started Tweeting - not quite sure I get the point, but I'll give it a go

Get yourself on Twitter they said.

You'll love it they said.

Err . . . OK, so giving it a try @DachshundLoony #dachsundmad

Haven't figured out the point of it yet - can anyone advise me why we Tweet?

Had a google and even the CEO of Twitter himself wasn't entirely sure!!
