Based on the quality of some of the new question we see every day, some users think we collect trash here on Arduino SE. But we don't collect it all really. Stack Exchange system has a cleaning process nicknamed Roomba (as the robotic vacuum cleaner). Roomba deletes closed question without answer 10 days after asked. Roomba deletes unanswered questions with negative score 30 days after asked.
Today I made for me an overview of questions count based on close state, answered and score. There were 23764 questions total at that time. I used advanced search with queries like closed:yes answers:0 duplicate:no score:1..1
.
