Not a well constructed instrument IMO.
I do ALL my shopping practically on line. I have more on line friends than real friends. I'm off and on all day--hard to put a figure onit, as I'm at my desk at work a majority of the 9 hour day and the net's always "on". When I come home a good part of my evening is catching up fully with things I couldn't while working.
But do I think it's a problem....no. Because when I actually ahve something I want to do with a real person, or an exciting alternate activity, the Internet doesn't somehow beckon to me to forgo other such things.
I think the computer may be the downfall of us all eventually though..
why? Because we're becoming so dependent upon it, once cyber terrorists find a way to really f things up, we're going to be in serious trouble.
Financial and Emergency System Collapses, Power Outages Oh My DOOM I say
But really when one thinks about it...well hmmm...we better just stay skilled in the old fashioned way of doing things.
