Lines up Twitter 'naysayers' against wall and proceeds...
... to smack them upside head with clue stick.
Whether or not uk.gov can figure out whether Twitter is useful to them or not, is neither here nor there.
Any geek worth their salt who *can't* understand how to leverage Twitter isn't actually worth their salt.
It's a typical knee-jerk reaction (with emphasis on the word jerk)
Because they see Twitter as being full of marketing bunk and the miniature of peoples daily lives, it's dismissed as dross and a waste of time.
Unfortunately, they haven't got the common sense to look further and to see exactly how useful twitter can be when LEVERAGED correctly.
The sheer amount of useful links I've got from Twitter is incredible - you just need to FOLLOW THE RIGHT PEOPLE!
Here's just one example - 123reg is using their twitter account as an informal help desk - twitter users post a question followed by @123reg and 123reg can respond.
It's also a great social tool for your mates - you can see who is going where, what they are planning etc. as a group.
If you can't figure out why these examples are useful, sorry, your stuck in the past.
