If you make a website for programmers, what is important?

Question

Web development

When creating a website for programmers, what should you pay attention to?
What will be important from the usability side?
What can't be done without?
The site is dedicated to: online learning, programming level testing - theory and practice, different programming languages.

Answer 1

There are hundreds of such sites. What is unique about your project?

Answer 2

The community and the material are more important)
If testing, then the value of the test, solidity, and respect for the certificate are important.

Answer 3

pay attention to new languages ​​and less popular ones - so you will have a core that simply has nowhere to go
very important is pure cross-browser semantic, if possible, valid layout
_fonts_ - let the designer fuck and select normally readable
image fonts: if there are 0 and / or all of them for the whole design will be packed in base64 - fine (before packing, you also need to optimize, by the way)
we don’t need prettiness, but we are not alien to them - shadows and roundings using css3
cannot be done without a freebie :) and zest

Answer 4

easy-to-navigate guides. notes ala php -> string functions, c++ -> OOP.
Q&A, ratings.

Answer 5

check out stackoverflow.com,
very cool in that regard too

Answer 6

It's very cool if the site is useful for programmers of different levels: both for beginners who are just learning the basics of a particular language / paradigm / programming in general, and for pros and programming enthusiasts for themselves, for fun. This is very important, because it is often difficult for beginners to find useful material on programming sites, forums, and the community, and the community is not entirely friendly.
In this regard , stackoverflow.com/ is cool , because. sooner or later, any person will receive an answer to any question. But, stackoverflow is only q&a, no testing or tutorials.

Answer 7

For noobs - reference books, recommended literature, ready-made solutions and algorithms for common and key tasks. The ability to ask noob questions (and look for answers to previously asked ones).
For the rest - news and reviews of new technologies. Discussions of a technical nature (although what is already there, holivars mostly). Well, questions, a little less noob character.
It would be great to throw ideas for those who wish to practice in their free time. You can even do it in the form of contests (who is better at coding an mp3 player in python, or something more original, but in any language with a memory limit).
Although all this IMHO can already be found for so long, but it is easy to implement through a regular forum.

Answer 8

On the "usability side": make hierarchical CNCs.
