Is the web changing the way we think?

A nice story on BBC by Bill Thompson (http://news.bbc.co.uk/1/hi/technology/7459182.stm) suggesting that the availability of small chunks of information on the Web is limiting our reading and thinking - now, I'll be the first to admit to a short attention span and it'd be lovely to use this as my excuse but I'm not so sure...I think that a lot of people (maybe not the younger people so much) still print out anything which takes more than a couple of minutes to read, so I don't think we're doing all our reading on screen...and in a way, the Web has made it easier to discuss issues and be exposed to other people's opinions. But maybe there is something in the idea that we maybe accept information from others without thinking too hard about the quality, validity...? Something to think about...
