There is so much in the article, that instead of picking from it, I would suggest these points. The idea of the Wiki is to create a free encyclopedia on the internet that will never be controlled from the top down by the elites. There is nothing to stop conservatives from posting so the argument it is liberal is only true to the extent that conservatives fail to act in their own best interests. Some facts sometime are wrong or slanted. The same is true more so with the controlled media.
Finally, the postings on Wikis are generally clear text, which is not the most efficent manner to move a virus or trojan. It seems the author may be suggesting the concept of a meme as if it were a virus. Or, maybe someone in Israel would prefer we don't read material from that partucular free site.
Remember, in the long term, that site will save you from spending hundreds of dollars for your kids to have an expensive set of out-of-date books.
