Quite often I look in the sandbox. Sometimes you can get really valuable materials there. For a couple of authors, I even had invites, since I wanted them to continue to be able to share their compiled thoughts and ideas on a larger scale. Recently, I even noted a slight improvement in the quality of posts (if this is not a temporary or accidental phenomenon). Somewhere, at last, they began to reinforce posts with graphics, somewhere to present in a more understandable form and a pleasant reading presentation. But… Maybe I'm wrong, but people are trying to focus on common interests. Looking for topics that would catch more people. Do not miss any events to play on them, and so on. For the most part, this is similar to chasing an invite. And only a few want them to be heard, so that really sensible and weighty ideas can be discussed with others. Not comments, not abrupt messages, but a lot of work done. And I like these people. Sometimes, they are much more pleasant to read than the narrators of the events in their own words.
Therefore, I would like to wish to put to the public those materials that really concern the authors. Yes, these materials can sometimes not completely fit the subject of the resource, but if they are really interesting, then it is stupid to think that they will not be appreciated here! Habr is a versatile resource, and many topics, at first glance, not thematic, find their own nook among many communities, even if they do not completely touch them.
Just decided to share my thoughts. Do not blame me.
