As many people have alluded to, genuine computer skills are very important now. The existence of courses such as the ECDL shows this; it is not enough to say simply "computer literate" on your CV now... employers often want to know exactly how computer literate you are (which is entirely fair and valid, because being able to make a pretty Bebo profile is not what I'd call a 'transferable skill').

On the flip-side of the argument, I am sure we have all seen many protestations over violent video games. Beyond that, people are now complaining about kids getting addicted to web-games in local cybercafes, with very genuine concern that it could even lead to gambling habits in the future. On a personal note, I am rather appalled at how the number of online Bingo (and similar) sites has ballooned lately (there are numerous TV adverts for them here in the UK). I do not begrudge the choice people have to throw away their money as they see fit, but particularly in such a financial climate as this, convenient at-home gambling -- often under the guise of a purely 'social' activity -- is rather a cruel enterprise.

As with everything, moderation is the key. I myself have fallen victim to over-use of computers in the past. Mind you, I don't even rememeber what I did on the computer all day before I had an 'always-on' Internet connection! Perhaps one of the key skills that is not being taught is the most simple of all... how (and when) to switch it off!
