If we all stayed away from Google, most of us never would have found this site, and many would not be half as well informed as we are.
Google is an essential part of 21st century life, and - in my view - a marvellous resource.
All the advice you need (though my guess is that you know it already!), is to use Google carefully, thoughtfully, and selectively.
Yes, there's a lot of twaddle out on the web, and Google can only find what you tell it to find, it will not vet the sites for you (except for malware, but that's another story). But there's a wealth of high quality info out there too, probably enough to make your head spin.
There are, of course other search engines, but Google is probably the best at the moment.
Disclaimer: I have no shares in Google, nor any other interest, except finding the info I need. ;-)
