@wbezs I can highly recommend checking out the closing keynote to learn that Rust is everywhere at Microsoft now. That was cool to see!
Similarly, Fastly is all-in on Rust as well. They are one of the project's biggest infrastructure sponsors, and it was great fun to catch up with them at their booth. (They also gave a talk.)
But I think the biggest change year over year is seeing how many attendees now work with Rust professionally. A few years ago, it was almost an exception to speak with folks using Rust in their day-to-day. Now it's way more common...
And regarding the community, I just love the vibe at #RustNationUK. It's a fun, diverse crowd of people. I really enjoy chatting with so many folks with vastly different backgrounds. 😊
