Is Twitter rude?

I am frequently upbraided by Next Door Kate for using my iPhone too much in social situations.

Yup, it's so good that very often it's too tempting to dive into the various virtual yet social universes that this device offers to me by virtue of its being the #1 way of accessing the web.

But she does have a point: increasingly we're becoming permanently semi-connected. We don't all devote our attention to the task in hand, preferring instead to twiddle with our phones to check email, twitter, texts and so on.

It is, in many ways, plain rude.

But at a recent conference they asked for questions and contributions to the panel via Twitter. These were then posted on a 'Twitter Fall' app on the data projector and the best questions creamed off (so to speak).

Everyone in the room was head down, tapping away. But we got some good questions and some good banter going. Twitter made it easier for people to ask questions - it took away the embarrassment factor.

And that's got to be a good thing.

Oh - and no-one thought it was rude. Although it did feel like a totally different way of hosting a conference.
