I think it's mostly
that some of us have an overwhelming urge to be helpful when we can. We know and understand computers to a degree that often amazes other people. We also understand just how frustrating, confusing and frightening malfunctioning hardware and software can be to the average user. So we feel an urge to offer to help.
And what's wrong with that? I think that it's an admirable trait in a person and one that's sadly lacking. A touch of kindness, sympathy or assistance can do a lot to make someone else's day just a little better.
But that's just my opinion, and it's one that doesn't seem to be much in vogue anymore. Instead of helping, everyone's petrified that if they try to help they'll get sued, robbed, mugged or worse.
Edit: so speaks someone who, at present, can't even get a tier 1 help desk job... So take my opinion for what it's worth.
