Rather than creating a website to kvetch about the contents of one domain, I suggest you and your collaborators' time is better spent curating a set of resources that teach what you consider valid information that can be used by people wanting to get started in web development (it would also be far more beneficial to the web development community). That one collaboratively edited directory of peer-reviewed resources would create a one-stop-shop for people looking for the best material on a specific topic or niche. By web developers for web developers. Put those collection of related resources on MDC if you must (you say it's editable by anyone, so all your collaborators can participate at will, and have an aged and already authority-status starting point right on your doorstep). One of the hardest things is to find resources for the beginner that teaches them high quality web development from scratch. Create a map for others and lead the way. That I feel is a far more constructive approach than this angst-ridden site you've spawned. And it has a more immediate benefit of linking to existing and already indexed material on the web, and add/aggregate more authority. A link from the zeldmans, heilmanns, sharps & blawsons and malarkey's of the web development community, and the reach they all have to a multitude of web developers can quickly give a high-quality curated resource a starting boost towards ranking the right material higher. Since if all your collaborators are already heavily involved in creating web materials covering the subjects W3schools teaches, then there's already a set of authoritative sites existing. Those can all point to your master curation site, and consequently pass on existing google juice to those materials that exist and are fit for purpose. Taking off W3schools from Google only promotes result number 2 up to the first place - is that really an improvement?
