HTML5 Custom Data Attribute
made a site-wide change of format. This:
<s class="deadurl" title="accessed:2006-01-05; defunct:2011-06-12">http://example.com/index.html</s>
is now this:
<s data-accessed="2006-01-05" data-defunct-date="2011-06-12">http://example.com/index.html</s>
this is a better format, using HTML5 Custom Data Attribute. However, now the user can't see the date accessed. Before, reader can see it when mouse hovers over. So, it's a hard decision to make.

Web Design Idiocy: Non-Copyable Text
one of the idiocy of web design is this: a piece of text that you cannot copy. Usually the title. Here's a prime example: 〔Introducing WebSockets: Bringing Sockets to the Web By Malte Ubl, Eiji Kitamura. At www.html5rocks.com… , accessed on 2014-01-04〕 (must use Firefox.)

Meaning, to the user, a site will have dynamic info, auto updated (most social sites, are already this, e.g. Google Plus, fb, twitter, and any stock sites or sites with dynamic news. Also Google Analytics's graph is also a example. Basically any sites that has graph).
also, i predict JavaScript and Node.js will overtake backend.
Node.js is very young, but there are incredible amount of stuff and force going on. Agile is the word.
Node.js server monitor/auto-restart
to install a monitor for your server written in Node.js, you can use nodemon. It'll watch your server process, and auto restart it if it crashed. It can also restart when source code change. Very handy for dev.

npm install -g nodemon
to start your process, do: nodemon nodeScript
type nodemon -h for help.

npm install supervisor -g.
