Time to catch up on some interesting links:

The End Of Free
Last week’s posting at the Scholarly Kitchen, discussing the idea of using free content as a marketing tool, and how some uses are reaching the end of their usefulness. I have a new blog entry there that will be out on Monday discussing Microsoft’s Bing and Google’s Wave.

Teen Practices
Very interesting set of observations of how teenagers use technology. Twitter and e-mail are boring things that old people use. Once again proving the idea that different tools are appropriate at different stages of one’s life and social development. This study backs it up with more numbers.

Landmark study: DRM truly does make pirates out of us all
A few weeks back, I wrote about the Kindle’s DRM:

By providing a product that suffers the limitations of lock-in and prevents users from doing the things they’re used to doing with books, Amazon is encouraging potentially honest customers to become copyright infringers.

This study offers further evidence for such behavior, and argues against DRM.

If Research Papers Had A Comments Section
A cautionary tale, in cartoon form.

Another Blogger Leaves the Seed Blogs
Some dissension in the ranks over at ScienceBlogs. Like we’re seeing at the Nature Networks, these clubhouses are hitting some rough waters.

For Wired, a Revival Lacks Ads
Interesting article on Wired Magazine’s struggles. It notes that Chris Anderson of “Long Tail” fame seems to make around $35-50,000 per lecture he gives to businesses. Ironic in that the concepts he champions seem to be failing at the actual business he runs.

And it wouldn’t be right to end one of these without some Web 2.0 cynicism/snark. So I’ll offer up Conan O’Brien’s painfully accurate Twitter Tracker, and this lovely Social Media Venn Diagram t-shirt.
