Just more proof that I, your humble correspondent, am better and smarter than you because I am a blogger.
This blog post I found from Political Animal claims that blogging will make you smarter. Highlight:
5. Blogging combines the best of solitary reflection and social interaction.
Research using the Lemelson-MIT Invention index found that invention is best fostered in solitude (66%); yet other research has shown the beneficial effects of brainstorming with a community of intellectual peers. So blogging may combine the best of "working by yourself" and "working with other people." Bloggers have solitary time to plan their posts, but they can also receive rapid feedback on their ideas. The responses may open up entirely new avenues of thought as posts circulate and garner comments.
Blogs combining the best of social interaction and nerdy solitary thinking stuff. No wonder I'm so cool.
