> so zooming in on a tile could cause it to get blurry, until your client requests a new, zoomed in tile. Now, they can serve tiles in SVG format, which scale better
They still are blurry, because openstreetmap.org uses a JS library that does not seem to support vector tiles :/
It seems to just not work in Firefox for me, it's the same for me on FF Android but in Chrome it's beautiful! Constant text size while zooming and it's super smooth.
Edit: It also weirdly doesn't work on Chrome on Linux for me either, only Chrome on android. Oh well, hopefully they can bring support everywhere eventually.
