seems like there's a bunch of clojure jobs in london

anyone know if there's a reason for that or is it just chance (or maybe I'm wrong)

maybe it’s popular for finance?

im not sure

London is a big city with lot of business opportunities, solid university background and a financial headquarter (at least pre-brexit). Financial support to invest in (more or less) niche languages is common. There's quite a lot of startup as well, with researchers employed from universities around the uk. Clj community is quite strong too, enabling new devs spreading the positive vibe. At least, this is what I see...

London is a massive service economy. Lots of companies need tech services..

Companies in need of services.. go to London 🙂
