Being a long time supporter of the contrarian position that blogs should not be narrowly focused, I would like to list some terrific blogs written by smart people that cover a wide range of subjects.
- Big Think--covers technology, innovation, social issues, education and everything else that matters
- Fast Company--covers everything from current affairs to cookbooks and the things in between
- Ars Technica--covers technology but frequently discusses science and the legal issues related to both
If you do not remember, many great ideas come from the point of intersection of multiple disciplines. Broaden what you read. These blogs may help.
