The algolia search seems very good in my opinion, I rarely simply can't find a post I remember and want to look up again days or even months after noticing it. Of course that is a proprietary search, isn't it?
At least it's a separate problem than the one solved by HN software / news.Arc (and probably Telescope, too).
The major flaw with most of these sites (and especially the "curated X Y Z" versions) are they go out of date or just don't build up a community and wither and die with out of date information. That's the real trick.. not just delivering the information.
Looks like hackr.io is pretty close to what he's asking for, but the first category I picked to look into I found only four articles, with none having more than two points from upvotes.
A good tutorial might take hours, days or weeks of my time. In that time, I am not engaged with your site.
Good luck.
- HN hasn't annoying ads. (How will you monetise it? Because you must monetise it somehow in the near future and we have already a lot of 'code schools' where people pay a fee to access).
- HN is his community. No community and your site will die. Many clones of HN have already died.
Anyway good luck!
Is there a real problem that we're trying to solve here?
The original idea could (if a community formed) solve the PHP problem. If a true beginner programmer decides to learn a language (I pick on PHP but it can happen with any language), the true beginner has no context with which to evaluate learning resources. Hence, you end up in the situation where beginners learn from bad code.
Categories and tags worry me because it sounds chaotic, but it could go a long ways towards solving the problem Zed Shaw articulated in Early versus Beginning Programmers.
Or we could just post some of our tutorials here! This is an introductory one I wrote covering the basics of HTML, jQuery, and making a ToDo app with my database http://gun.js.org/web/think.html .
