Previously, it used to be that if you asked a question on Stack Overflow and didn't immediately get a good answer, you could leave the site and check back within 2-5 days, and chances were that you would've received more answers. I think this might've been accomplished by showing randomly selected questions from a user's favorite tags on the homepage, as opposed to just the newquest questions.
However, if I ask a question now, the only views/answers I receive are within the first hour, if I don't get a good reply within the first hour, it basically means I wouldn't get any other replies. I've also been noticing fewer views and more unanswered questions on other people's profiles than before.
Now it seems like the only way to receive an answer after the first 1-2 hours is to put a bounty on that question.
Has anyone else also noticed this? Has this been caused by an update in the last couple of months/year?
