Horizon highlights – Blogging for profit, more 3-D movies, recycling PCs

Our regular roundup of sci-tech stories from across the Web includes: the secrets to blogging for profit, major push from movie companies to have more 3-D movie theaters, and how to lay your PC to rest the green way. Let’s kick it off:

Jobs 2.0: How do bloggers make money?
"Bloggers create 900,000 blog posts a day worldwide, and some of them are actually making money. Blogs with 100,000 or more unique visitors a month earn an average of $75,000 annually – though that figure is skewed by the small percentage of blogs that make more than $200,000 a year." [via Slate]

"Quick – name the invention that has done most to redefine our place in the universe. Hint: This invention was also the most seditious, blasphemous instrument of all time, shaking the very foundations of society. The answer, if you haven't already guessed it, is the telescope. It's hard to believe that this instrument, often sold as a cheesy toy in gift shops, is perhaps the single most important scientific instrument of all time." [via Wired]
