I apologise in advance, as I am pretty sure some of my personal preferences for a decent round-up are mutually exclusive or just extremely onerous on the person doing the compiling!
I don’t mind round-ups being a daily thing; I’ve noticed that the time they get released isn’t in replacement of a new story, so as I’m concerned you are more than welcome to keep producing them at whatever rate you wish.
I also don’t mind what the topic is, although a topic I have no real interest in (for example anime, gaming, D&D etc) I might not read straight away.
Ideally, the stories within the round-up need to be different from each other, or at least have something about them that sets them apart from each other enough to feel different. So a round-up of “I don’t work here” might be very tricky to do as they all more or less follow the same formula. Whereas a story about allergies has a fair amount of potential (customer faking allergy, worker disbelieving allergy, customer not realising strawberry yoghurt has strawberry in it, etc)
Also, it would be nice to have the round-ups to have a lot more of the older stories than recent ones. I don’t mind recent ones in the round ups, but those are still fresh in the mind; I’d prefer to get a blast of nostalgia. It might be best to make sure you have a lot more old than recent.
Don’t forget variety… sometimes we have stories that have been in more than one round-up (and not just those that have been in Best of Month or Year)
And I shall don a dirty tan trench coat to finish with
Oh, one more thing… it would be good if you could check the comment section of the stories you are selecting. It doesn’t happen very often, but occasionally you select a story that has received a lot of, um… negative feedback. Including those in the round-ups just feels like trolling!
Just read back through my thoughts… yup, I’ve definitely created a lot more work for the person who has to implement them all. Sorry; feel free to ignore!
