Let's begin this post with some facts. From the site analytics, which is viewable to any user with 5000 or more reputation points, we can see that, from 1st to 27th August, the total number of posts in our main site has been of 89. But this month we have only 6 voters, that is, only 6 users have voted more than 10 times this month (this includes up and downvotes).
Edit: It's been said in comments that this can be due to a seasonal reason related to holidays. However, I can assure you I have observed a similar behaviour in the previous months. Maybe we had 7 voters instead of 6, but not more.
This implies that posts are generally receiving few votes. In my opinion, this is an important problem. Well, this is my personal opinion: it could be that other users of this community think that's OK: I would like to know what do you think.
In my personal view, one of its consequences is that askers (and also people who use our site to learn or to search information) are sometimes unable to distinguish good answers from the ones that are not so good. It could be that, according to the community, it's not that way and that answers are generally receiving the number of votes they really deserve. I really don't know what the community thinks, so I would like to know your opinion about that.
I re-post an extract from this answer of another Stack Exchange Meta site, which has achieved a large consensus by the community of such site. I personally find it relevant:
The system doesn't work if people don't vote.
Voting is literally The Thing that allows Stack Exchange to work. Good answers are brought to the top, singled out in some cases. Seeing that the next answer has nearly-as-many votes means you shouldn't stop with the first answer, and in other cases where you see a steep drop-off in voting (at least for older answers) may indicate that you can stop where you are. Remember, Stack Exchange is built around answering questions for all future purposes, as well as for the initial person asking it. Part of that means, at some point, saying "you've gotten the meat out of this topic; there may be some more useful ideas, but you have read the things that this community thinks are best."
Well, I believe most SE sites work that way (at least the ones that are considered to be "healthy") and I wonder: is this also the way our site is working?
For all this, I have decided to open a discussion to invite our community to find some good reasons which can motivate us to vote questions and answers.
Even if we think that the number of votes that posts are receiving are generally OK, I believe that having such a list of ideas may be helpful to all us so as to vote more consciously. And even if the reasons to vote questions and answers are very clear to some of us, I believe to have a list of such reasons which has achieved the consensus of the Italian.SE community may be useful for future reference.
Let me remark that I believe that a post with very few or no votes doesn't necessarily implies that is unuseful or uninteresting to other people. Some of the questions of mine which have achieved the famous question badge (more than 10,000 views) have only 1 or 2 votes and a quite significant amount of the ones with the notable question badge (more than 2,500 views) have 1 or 0 votes. I would recommend users not to stop writing posts just because they are receiving very few or no votes. I had to convince myself of this, otherwise I would have stopped writing answers. And about questions: is it really such a problem asking about something that interests few other people in the world?
Last but not least: thanks a lot to everyone for supporting this community and please keep voting!
