Daily Bits is a useful site for me. I find great information on a variety of topics ranging from Internet, browsers, fun stuff, PC security, search engines and general stuff.
There is more than the list mentioned, buddy. Visit the site and I am sure you will love it.
Some of the stuff I just read are:
Microsoft’s online training programs
Google crawlers are programmed to index in images. (this is a very interesting news)
How to find jobs in social media
I have subscribed to the Daily Bits feed immediately and I am looking forward to amuse myself and also gain useful knowledge.
