The internet is a boon for anyone who wants to read up or learn about, well, pretty much anything. It’s easy to get distracted by the latest cute cat or gossip, but if you ever feel like digging your head into something deeper, have a look here. These are a few sites I’ve stumbled across which people may find of interest

Google’s Code University: Learn how to program in various codes for free.
Google Scholar: Search many academic papers.

W3Schools is a great place to learn various programming languages for free.
TED (the Technology, Entertainment, and Design conference) offers videos of its fabulous 20-minute lectures & performances free online.
Wikipedia is a great starting point for most inquisitive escapades. Not to be overlooked.
The blogosphere itself. Following a blog on a topic of interest is one of the best ways to learn the ins and outs of that topic. Google searches for “(your topic here) blogs” will probably lead you in the right direction.
