A few points:
-
MAU is a problematic indicator for the fediverse. for example misskey does not report it properly (see the github), for some open source platforms like lemmy the definition of active users is too strict IMO (i would count anyone that logged in, but that is a different discussion).
-
if you look at the growth rate of servers it is pretty good i would argue. i calculated a around 30 percent annual growth in the last few years. if this was a stock or a ETF or a pension fund this would be considered a very good growth rate IMO.
-
generalizing about the fediverse is not very useful IMO. look at specific software. when i thought of things i thought could be good for lemmy i submitted issues and things got implemented. if i can do it a lot of other people can. feedback is important.
-
you are asking people who are already satisfied with the fediverse platform they are using. which could be useful but i think you should be asking people who are not using it. find accounts you like that make you or others stay on proprietary platforms. that you think provide high quality content and ask them what they want. or even have a discussion about what features to design or experiment with. for example i saw people on r/newiran (subreddit for the opposition in iran) wanting a feature to show from which country someone posts in (like what twitter recently added). this can even just be a unofficial plugin people can install. these kind of things could provide a competitive advantage that will help people use the fediverse on top of what they want or need in proprietary platforms.



according to the internet he has a return on investment of about 9% in the last 10 years (CAGR). msci world index (which is usually used to compare to see how well a fund performs, and has index funds which track it) made around 13.65% (so a lot higher).
So i would not put too much attention to this guys opinion, sure maybe he is taking less chances (less scary drops in the fund value that some investor don’t like) but looking at the graphs it doesn’t seems that way.
I think it’s a good to do this exercise , a lot of active investing seems like snake oil (although probably not all of it, at least according to some data and research). someone even wrote a book on the subject called “Where are the Customers’ Yachts”.
