The platform has significant processing delays. It degraded significantly last year when they were grooming the platform for sale. It has improved under the new management team but they are trying to salvage a botched update project.
I did a few years of IT Project Management during the dot.com years. What you are feeling/seeing is a project fail.
They had a working platform a few years ago that was doing stats in real-time. However, it felt dated and it was structured towards a "Writers Collective" economic model.
It was not attractive to investors and or buyers. How do you monetize that?
So, the wave of "upgrades", changes, and "new features" of the last few years. If you have ever done a major software project you are already wincing. These kinds of projects are fraught with peril.
What we have been living through is that upgrade. From what I can see they botched it. It's probably over budget, over deadline, buggy, and slower than what they started with.
But, now it will read your stories out loud. So, you can pitch Medium as a sort of Audiobook or podcast site.
Now that Ev is gone. The new guy is getting the project under control and trying to stabilize the platform. But yeah, the stats are extremely laggy and they update in weird patterns as batch updates are done at different times.
