I have always hated pre-rendered tiled maps. They use lots of space both on servers and clients and thus cause related problems like slow download speeds, limiting downloads due to big size and you can't easily change colours or select displayed details to name a few. I hope this will become a new standard on serving and using openstreetmap data on various applications.
@Tikkis Well, these are pre-rendered tiled maps, if you think about it. They’re just pre-rendered to vector layers that can be toggled and styled individually, instead of rasterized PNGs with a fixed style.
The _real_ innovation is the file format & being able to use range requests.
