  • Way too much AI glofication

    Oh my god, it is so annoying. No AI won’t change everything, it has its place but what are you doing? I mean, none of those AIs are at least somewhat profitable. How long do expect this to continue?!

    Also, don’t put „you might also like“ in my podcast queue!

  • Stop “you may also like”

    The SN content itself is great, but the repeated addition of extra, “you might also like” content is super annoying. If I wanted that, I’d subscribe to it. Please stop polluting your feed.
