Charting the Cosmos


Cosmos URLs by week (.png)


Cosmos has been up and running since the start of 2022, collecting gemlog posts and other feed entries around Geminispace. I thought it would be interesting to take a closer look at the data.

Added more charts for unique author names by week and unique URL roots (domain + username) by week.

Important to note that while there are about 150 visible monthly active *posters*, there are many more who read things on Gemini but do not post regularly.

@satch Exactly. There is no way to estimate the total readership... Except maybe from ew0k's server logs?

Updated with a fifth chart that tries to show churn of new vs. inactive gemlogs. This is purely based on first and last posts (as of today). More accuracy could be gained by checking whether the URLs are still working.

If you want to estimate anything, you need at least IP addresses in your log files, which is not very privacy-friendly and re-introduces parts of the performative WWW.


But I know that statistics are tempting, even if they are not needed or very useful.

@michaelnordmeyer Yeah, IP addresses are the only possible metric. However, since that is only knowable by each individual server, it's pretty impossible to estimate a total across Geminispace.


The idea of these estimates is just to look at the total aggregated activity and not any individual capsule's "popularity".


(For the record, Cosmos is not logging anyone's IP addresses.)

@skyjake I looked at the DB a couple of hours ago because I was messing with SQLite databases anyway and noticed, that you also have non-page resources like images in the links table. Does this make sense?


🕹️ skyjake [OP/mod...] · 2023-06-07 at 19:53:

Images can be submitted to Antenna, too.


The links table isn't particularly filtered, apart from next/prev kind of navigation links that some people use. When Cosmos collects links, it has no idea whether the link target might be part of a feed.
