Since they've redesigned the Chromecast promotion web site is there any easy way of finding content sources that work with desktop web? It all seems to be very phone app oriented.
What's slightly annoying is that sites like Tunein Radio get promoted because their Android App supports Cast, but their website player doesn't (yet).
I guess iPhone users are probably in a similar situation as there's bound to be sources with a Cast ready Android app but where the iOs version doesn't do Cast yet.
You could send them feedback from here if you're not keen on the new layout?

Chromecast works with "cast optimized" apps, initiated by modern android and iOS, PC/MAC, and chromebook. Modern androids will also handle "cast screen" - a mirror feature - although it imposes a heavier load on the network.
