I noticed that during the last year the quality of our site (according to the official quality metrics of StackExchange) deteriorated. You can have a look at our current Beta status.
We can't do much about the number of questions per day, but according to site statistics we have a steady influx of new users and visitors that didn't change for several years. But the number of unanswered questions increased from less than 5% (according to my memory) to now 10% and the average answers per question dropped below 2.
I'd like to invite all of our members to have a look around the list of unanswered questions and see if we can answer some of them. Maybe there has even been a similar question more recently, which might allow us to mark the old one as duplicate and clean it up.
Let's see how much we can improve the statistic till the end of the month.
