Have you noticed that I have stopped commenting most of the stories on the internet? That's because other sites have started making a business out of it, and are doing a great job: techcrunch, engadget, gigaom, paidcontent, etc.
However some of the stories I find interesting are bookmarked on del.icio.us, and you will get them in my feed:

Sometimes I put in a quick comment, or highlight a passage of the article. There you will get a view of part of what I'm reading, analyzing, reflecting on...
Enjoy. Please let me know whether it's useful to you or not.
