I feel like I am taking crazy pills when reading the other responses, but come on, this seems like normal human psychology when being exposed to a new thing over and over. It feels new, it solves everything, but then over time you get bored with it. Attempting to proxy it with "account freshness" just masks the problem. It's the reason why people tried to quantify it with stuff like https://github.com/ninjahawk/livenerf because the pattern you are referring to is a known bias.
