Vladimir, it's not good form to post an entire article, not to give proper attribution and a link, not to write at least a little commentary of your own.

It's also poor form not to come back to your diary, read the comments, and discuss.

Since you don't seem to be around, I have reduced the article to several excerpts. If you want to choose other excerpts, you can do so.

Please note you should also place an introductory section "above the fold" (upper editing window), and the rest in the second editing window.
