I see the cloud of tags on the button of posts. I assume it is the most used tags in let say last 100 posts or days posts, but I am not sure if I am correct. Please correct me if I am wrong.
I know the meaning of tag. I think it turns good results when you are searching the whole CADTutor database. Before I was unaware that I can add tags to my post but recently I have discovered it and I add few tags (maximum 5 is allowed) to each of my questions.
Also what is its advantage and how one can utilize it?
