If you want to stay top of mind for a constantly growing audience and increase visibility, post every day.
If you want to amplify your launch, focus on the period before, during, and after the launch.
Before the launch, I would start with enough time in advance, around one month before, and I would personally post approximately (at least) twice a week.
But I think that in general, if you want to be visible within the forums, twice a week is bearable.
Ran the same comment through four threads over a month and only one kept generating views weeks later. The difference was not the reply count in the first hour, all four got at least one. It was whether a third person with no connection to me or the OP joined within the first two or three days without being asked.
If it stays just me and the OP going back and forth, that is engagement, not compounding. The one thread that kept going had someone unconnected join inside 48 hours, and that window is also roughly when the other three had already gone flat.
Curious if anyone else tracks this specifically, or if there is an earlier signal worth watching for before the third person even shows up.
