> you don't see the CTO coming to chat about it.

Speaking as the CTO at Element (and proj lead for Matrix), i feel like i've spent a bit too much time coming to chat about Matrix on HN over the years ;)

That said, I agree that Bluesky is doing well in terms of breaking through into mainstream awareness - much more so than Matrix (although obviously big-world-social-media is something of a different beast to distributed-instant-messaging).

The reason Matrix hasn't done better here is primarily economic: we spent too much time and money building out Matrix for everyone in the early days... and not enough time focusing on building either consumer (as Bluesky has) or enterprise or government specialised products. We then got traction at Element on the government side of things (https://element.io/en/matrix-in-europe etc) as it turns out governments love their digital sovereign communications - which in turn meant that in order to get sustainable and survive we had to focus hard on building stuff for that market. Now, ideally the stuff which works for Govt would work for mainstream too (after all, we're generally competing with Signal and WhatsApp, which are of course mainstream apps) - but in practice it has been hard to get that balance right. You can see my <del>TED Talk</del> FOSDEM 2025 talk about the road to mainstream matrix here: https://www.youtube.com/watch?v=lkCKhP1jxdk

Meanwhile, the plan on Matrix is to get to profitability via Govtech and then invest the money back into improving Element (and Matrix) so it also works well for mainstream usage - so hopefully we'll get back on the radar then. It's a long haul though. Meanwhile, kudos to Bluesky for getting to focus on the mainstream use case; I'm jealous, and I hope they find a good sustainability model!
