Sorry, I misunderstood and thought you were trying to correct me! Thanks anyway :)

I would agree, but I think the difference nowadays (had to look up I got "nowadays" right, seems I did!) is that people usually want a quality filter in front of them (like upvotes, likes, retweets or some other metric) rather than just having to judge by themselves.

In good ol' email threads, you always had to judge by yourself. In social media today, many assume quality because of metrics.

I did not know that it's "day" not "days". Not a native English speaker and have always been saying it "days". Thank you for correcting me!

Both could be correct. Here I think "day" could make more sense. An example of the other case: "Back in the days of Fortran programming..."

If you leave out anything after "days" by just saying "back in the days" then it is like you are pausing. As in when you reminisce, "Oh, back in the days!" Maybe that is what the intention was.

In any case, the commentor was actually just saying that he thinks nothing has changed.

Either way
