I'm all for this. Especially teaching others. I recently befriended someone from HN who's been asking how to code in HTML and CSS. I directed to my github account and have been writing little tutorials to answer his questions over email. It really helps you get a better understanding of your own skills when you teach it to others. I'd also much prefer someone ask me directly than reading some tutorials online. There are so so many tutorials online that are teaching people the old, non-standard way of doing things. Basically, it's like all the tutorials from 1997 somehow get the best rankings in google for "HTML tutorial". Though it is important not to overestimate your skill level and hopefully you aren't passing along bad practices and techniques to others.

Other ways to move the web forward: stop supporting Internet Explorer altogether. That browser needs to stop being coddled and forced to get with the times. The difference between Webkit and Gecko rendering is almost a non issue but when you start having to support Trident then it's almost like having to code a site twice. Let's just stop supporting it and either let that thing die or force it to keep up. Version 9 and 10 are steps in the right direction but it can do better.

That said, we can't always drop IE support. Very high traffic, corporate, and intranet sites will still need to have support for IE for some time but all in all, lets drop it when it makes sense. Personal sites and even some business sites can work. I personally don't do anything to specifically support IE on my own business' website and it hasn't hurt me a bit. Let's take a risk here and there and drop IE support and move forward.

Moving forward is about more than just code though. It's also about user experience. A site with code that's 100% valid but is hard to use or uses distracting elements like gratuitous animations isn't moving forward. It's just building a site that looks like its from the 90's except with modern, valid code. That's lame.
