So now there are 900 questions with the deprecated tags.
There were 1000 such questions on August 25, which means decrease by 100 questions in about 10 months.
I will not post here again breakdown by tags - since I have done this quite recently. If you want to have a look at these numbers in the past: June 2, May 1, November 5, August 11.
