I first noticed it when it happened to me. Then I noticed that it's happening to a lot of people. Questions are frequently getting downvoted without the downvoters indicating their reasons.
The GenAI Stack Exchange community is still new, hence its contributors are new. We don't want to immediately drive them away. The environment isn't exactly inviting participation when the people letting you know they don't like what you have to say can't be bothered to drop a comment indicating what could be improved.
If I dare to speculate, one contributing factor could be readers' expectations. GenAI is a broad subject that everyone is curious about right now, and there are lots of non-technical questions being asked - which is fine! Questions don't need to be technical, but they should be answerable and on-point, and hopefully practical to others beyond the individual asking. Individuals coming from a more technical background might think that some of the non-technical questions being asked are simplistic.
I take the view that a question attempting to solve a real-world problem, as long as it is answerable in scope, and shows some effort and research by the contributor, is most likely a valid question. If it's not a good question, we can let the author of that question know - politely. If it's almost there, but coming up a little short, why not offer a suggestion to bring it up to par?
Besides the obvious step of offering constructive feedback when we feel a question is lacking, how can we encourage others to do the same in order to set a positive and inclusive tone for this still budding and malleable community?
