I like it and even the promoted content is quite often relevant (unlike facebook where I had literally 0% ads about anything I cared about in the decade+ I was on it; they can have to best AI people on earth, on paper, but they really seem to know nothing at all about me even though
they know everything about me so i'm not sure what those people are doing /rant). I often see interesting stuff, but I do curate who I follow (more and more); I am interested in retro computers, startups and programming language theory/formal verification (including the math). I hardly get stuff that is not relevant to those things. During Covid people talked about the politics (polarised vaxxer/anti vaxxer shouting matches from generally very, very smart people) which I ignored and even unfollowed some who just went to far, but generally it's good content. I
really hate the format it has; I wish it would auto-aggregate threads, but I know why it is the way it is and changing it would probably hurt it.
What does happen to every platform including twitter (and those are the people I unfollow the most) is that the 'internet marketing' people take over and use every opportunity to push in some affiliate link or product. Sometimes these products are good and welcome, but mostly they are just uninspired rehashes of other get-rich-quick drivel.
