To be clear, the time probably needs to be expressed via UTC / GMT or other time zone labels.
I regularly post across ~half a dozen communities, the most frequent being to my own, where I post at 9AM (UTC-4 / EST zone) so as to hit early risers in the States and afternoon surfers in Europe. But with other posts, I get the sense that it would be better to post later in the day to hit more viewers. I’m just not sure when that would be.
TBC, I usually use the PieFed scheduler to post, so it’s no problem for me posting at any time of the day.
Thanks for any insight!


I agree with you on the community distinction, but federation across instances should be quite fast, no? (like under a ~minute)
If we throw out the C angle, when might the most heavy traffic be across Lemmy / Piefed, or just Lemmy if that’s easier. Personally I get the sense that the lion’s share of traffic for Lemmy comes from the North & South American timezones, but that’s just a guess.
It should, but federation is definitely not perfect. Posts usually federate pretty much instantly, but I have absolutely had the occasional post that took an hour or more to federate out to a remote instance for whatever odd reason.
Similarly, I’ve seen delays in people reacting to certain posts in situations where typically there’d be at minimum a couple quick ‘nibbles.’ Had some of that just last week IIRC.
