I'm new to this part of SE, and read a whole lot of questions, really fast.
Often they have a comment like this:
Hi Lucas, welcome to GDSE and thanks for your question. If you want to know more about the site, please see the help center or ping one of us in chat once your reputation is sufficient (20). Keep contributing and enjoy the site! – Vincent♦ Dec 12 '14 at 15:39
for example over here.
As you see it is from Dec 12 2014 and of interest for nobody, not even to Lucas. Trying to find out, if there is useful information in the comment, I have to read it. It's doable if you cross such a thing one time per day, but not over and over again.
Can't such noise be removed automatically after one month for example?
I flagged some of them as too chatty but could have chosen 2 different reasons, as obsolete or not constructive.
