Up until a bit ago I could use a browser to find stuff at http://public.highfidelity.io/
I found this useful for looking for available scripts, skybox textures, models etc.
All of this has changed now and at best I get a bad key error, but mostly just a blank page. The assets themselves are still there because they still load from the same URLs in Interface. I suppose this is related to ongoing work on the marketplace but I still found just looking them up with a browser easier when using them for stuff.
I also worry that the content itself could eventually be moved which would break anything that uses the old URLs. Wonders if I should make copies of anything I use and host them myself?
