I signed up for the course, without ever watching the videos or reading the transcripts. A few minutes ago, I thought this might be a good time to finally get started. So I came back to the original LessWrong post to find the link to the course. But after reading gwern's comments, it's become clear to me that the course is not worth it.
Lesson: unless you have strong reasons for committing immediately to some time-consuming course or activity, wait until others whose judgment you trust have reviewed the course or activity.
Daniel Russell is doing a free Google class on how to search the web. Besides six 50-minute classes it will include interactive activities to practice new skills. Upon passing the post-course assessment you get a Certificate of Completion.
Advanced search skills are not only a useful everyday skill but vital to doing scholarship. Searching the web is a superpower that would make thinkers of previous centuries green with envy. Learn to use it well. I recommend checking out Inside Search, Russel's Blog or perhaps reading the article "How to solve impossible problems" to get a feeling about what you can expect to gain from it.
I think for most the value of information is high enough to be worth the investment. Also I suspect it will be plain fun. I am doing the class and strongly recommend it to fellow LessWrong users. Anyone else who has registered please say so publicly in the comments as well. :)
Registration is open from June 26, 2012 to July 16, 2012.
