What if we use number of days we didn't reply for each email in our inbox instead of just number of emails?
The obvious problem I have right now that I prefer to reply to the recent emails to keep the inbox number low, but it makes old emails to stay here for months.
@abcdw The problem with going round robin is that replying to an old email often takes way longer, because it's less likely to be about the most recent thing you were working on or thinking about, so you have to switch gears.
Also, there's a good chance that the subject of the old email has either worked itself out, or blown up (in which case you have newer emails about it.)
