hello and thanks for the new site. I’ve added some links to automated testing. You might be purposefully triggering some warnings to support wierd browsers ofcourse
The pagespeed and yslow tests still show a lot of oppurtunity for improvement: http://gtmetrix.com/reports/lesswrong.com/MwBG3tEn
W3C has some conformance to standards advice http://validator.w3.org/unicorn/check?ucn_uri=lesswrong.com&ucn_task=conformance#
W3C says rss tests pass but compatibility could be further improved: http://validator.w3.org/unicorn/check?ucn_uri=lesswrong.com&ucn_lang=nl&ucn_task=feed#
W3C says the site completely fails mobile compatibility (this is big for me since i browse it mostly through mobile devices with small screens) http://validator.w3.org/unicorn/check?ucn_uri=lesswrong.com&ucn_task=mobileok#
I hope the feedback in these tools can help further improve the site, and particularly improve the experience on mobile devices with small screens and limited data plans.
I have noticed that my lack of math skills put me at a great disadvantage. Telling people to go to khanacademy and do all the exams is a bit extreme, but maybe someone would be able to write a convincing post about how truly understanding math would help further understanding in general and lesswrong specifically.
Other than that i fully agree that we need a rewrite and re-ordering of the content to be more beginner friendly. I am willing to spend time helping out here but i do not know what to do.
