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:

• Some of Lemmy's servers/instances going offline could cause the total to go down;
• Post deletion could also contribute to the total going down.

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.

Hello @PatFussy@lemm.ee

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.
