I used to be able to ask a question on Stack Overflow and get 20+ views in about 2 minutes.
Now, I get less than 5 views in 2 hours.
Did something change?
The number to look at is the question age on the front page, which shows 48 questions.
Right now, the oldest question on the front page (at the bottom of the list) is 7 minutes old.
I have considered making this list dynamically larger as the site gets busier -- in other words, ensure that the range is at least 15 minutes -- but I'm not sure if people would actually scroll all the way down the page.
The question count ballooned much faster than number of users. For users who filter views by tags, more tags meant they are diluting your post's visibility; and like what Dani stated, your post get pushed off the front page much sooner than before.
There are many more users now in SO, and maybe even too many questions. Once your question moves to the 2nd page and subsequent pages, it will be less viewed, unless it's a good one, and people seek that exact knowledge.
Could this be an issue with GMT? I am Indian, and I'll post at night to get replies quickly and often get a higher view count.
