A few thoughts on editorials.

I do understand that writing good editorials is tough so I accepted that here and there they may have some issues, Some omit important details, some are overly complicated and some are written like authors couldn't bother less and just translated someone's solutions from c++ into English. But let's put it aside for a moment.

On the other hand, is there any legit reason not to post editorials automatically and immediately after the end of a contest?

It is really annoying to wait for an editorial and at the same time it seems a really low-hanging fruit that should not require much development.

The only possible reason I may think of is that an editorial may not be written yet at the time of a contest. But this is a problem per se. Why do we even have contests without prewritten editorials? It should be strictly forbidden to schedule a contest without an editorial. Just like you cannot hold a contest without problems, you should not be able to hold a contest without an editorial. I would think editorials could also be a convenient tool to verify the problems for a coordinator, strange it is not the case. Ideally I would also like editorials themselves to be tested by coordinators but that is probably too much to ask for now.

Anyway. Editorials are not optional/auxliliary or whatever. They're an integral part of a contest.

Note that given that editorials have to be written anyway, requiring them being prewritten should not lead to any additional efforts yet it will improve participants' experience.

The search on the site is terribly broken

Say I want to find all tutorials, I search "tutorial"

What I see is only four blog entries.

Even though there are plenty blog posts which have [Tutorial] in the title and tutorial in the tags, search dosn't show them. I kind of can accept that full-text search imperfect, that's ok, but even search by tag doesn't work

Just felt like gathering some data about hacks. Parsed around ~400 last contests
Probably it would be worth it to also include SFT, but whatever
