Well, this is a screenshot that I've edited slightly. I'm unsure whether I can claim copyright on this image. However, if the Fediverse Observer doesn't object, I would be glad to release it into the public domain (CC0).
I'm not sure exactly how the Fediverse Observer calculates the day-to-day totals, but my speculation for the dips in the graph is:
These dips in the graph confused people in my previous post, as the dips were suggesting that the graph represents 'new posts by day.' I edited the title in the screenshot this time to clarify it is total by day.
The dips in the graph could be caused by some of the servers/instances going offline, post deletions, or a combination of both.
The 90-9-1 principle may also be relevant here: 90% are lurkers, 9% are contributors, and 1% are creators.
I don't think that SimilarWeb includes app traffic in their estimates; they seem to focus on web traffic only. App traffic would be interesting to track, though.
