Hi, With new startup we've decided to make some stats of websites. It is based on analysis of almost 4 million domains - various languages, scripts, tlds and so on. http://www.statino.com/statistics You can notice incredibly dominating position of Facebook social plugin (used on 60,3% websites!) and how far behind is Google plus - 4,71%. Twitter appears on 21,67% websites. 82,7 % uses external CSS, and almost 30% jQuery. XHTML 1.0 TRANSITIONAL has dominating position in document types, but HTML5 has already 19.53% share - I think that it only takes time to be number one. We can tell that UTF-8 is a standard in encoding types - 71,93%. Almost half of websites needs time below 1 second to load - so if your site has worse score - I think that it's something to change... I hope that it will be useful for someone. Thanks.
