I never use questions for you either.
I like to weed through the New Activity because sometimes I ask for an update and I want to see the response, and it may be a question from a while ago so it will be buried down in the feed. Sometimes I will click on “Follow” to follow something and if there are a lot of responses on it, I may want to dedicate some time to reading it all. So a few days, weeks or months later when I have nothing to do, I may go back and read the thread. However, I may also change my mind and say “screw that” like discussions on religion or discussions on the Malaysian plane that’s missing.
