I am not sure the founder is reading this. I tried googling but couldn't find it - I recall the hn handle being something like Atheon. Not that hn sends mention notifications.
Matrix is something that had my eyes lit after years or being burnt/disappointed by communication apps (Signal included). I had converted/migrated a lot of people to it (I mean of course they didn't "convert" but they had it and were replying to me) from a country where WhatsApp is essentially "basic need" today – along with water, air, food, and shelter and that too in an era when it was not even stable. After that I just didn't know what the hell happened. Matrix, Vector, Riot, Element – things just kept happening. App was never an end user app and it became very clear that it was not the intention either. To be honest it didn't look like a replacement for something like Slack or something like IRC either. It was trying to become something which it seemed/seems has no end goal or destination i.e a clear roadmap. As if the goal is to develop cool features and just put them haphazardly together which I am afraid often results in something Mary Shelley wrote.
I still login from time to time and I don't understand what is happening. Something I see this notification, something that, sometimes I see there's a message pending, sometimes I see I have a chat recovered (old/stale; because there's no one I know uses it anymore), sometimes I see a certain chat is not recovered because some verification or decryption (or something) failed, sometimes I see (or understand it) that I might another active and verified device to recover certain messages. I had created some groups and of course they remain abandoned - but no, few og them were filled were porn and the kind of some was scary because that vector/riot/element account is connected to my real ID including the email and I was scared shitless. I tried deleting them but I couldn't. Next time I will try harder or just try to make it private after kicking everyone out. I will still keep the account. Never say never :)
I sadly have moved from writing enthusiastic to sad to disappointing comments to not even paying attention to it when there's a Matrix/Element news now. I think I don't even notice it. I think that's the worse kind of eventuality in this context. Anyway, I wish you all luck and I am sure you all know what you are doing.
