I have noticed that since recently questions that are tagged with favorite tags are popping on the top of the main page (http://stackoverflow.com) even if those questions haven't been modified for a long time. Is this some new feature I didn't understand about? If so how it can be disabled as it is extremely annoying and it completely destroys the usability of the site?
The issue is even more serious than what I initially thought. Removing my favorite tags doesn't solve it and I continue to see old questions on the home page from my older favorite tags. I really hope someone on the SO team would provide an explanation and fix this horrible bug.
