This is something I've noticed for a while but I wanted to wait until I earned a Steward badge to show I have some 'skin in the game,' so to speak.
Of the review queues, Late Answers (LA) are by far the rarest. Typically about 20-30 appear in a given day and I count myself very lucky if I get to review one. However, I have noticed that a handful of users- all of whom have the corresponding Steward badge- account for the bulk of these reviews. In fact, these users typically review three to five each daily, though it is not uncommon for several users to review as many as eight or more. Unlike other queues, I feel the scarcity of LA makes this behavior inappropriate.
LA are fun to read. People often spend more time on them than run-of-the-mill answers and occasionally you see someone come back after a considerable amount of time and answer their own question. They are also a good way to interact with new users and to encourage patience and perseverance, two important mathematical attributes. I think more community members would benefit from reviewing them.
To summarize, here are my requests.
If you have a LA steward badge, please consider not reviewing LA as soon as you see their notifications in the queue. In particular, please do not review many LA in a single day, as this deprives others for no tangible gain.
Update: with the change to Steward badges, I think this is less of an issue, but would still ask those with the LA Steward badge(s) to show restraint.
