Nosta profiles now show live activities (via the work-in-progress NIP-53).

Example:

https://nosta.me/npub12hcytyr8fumy3axde8wgeced523gyp6v6zczqktwuqeaztfc2xzsz3rdp4

One click and you're off to view the stream on http://zap.stream.

Some more tweaks to come, like highlighting when the user is currently live. If you have more ideas to improve this, add them here: https://github.com/GBKS/nosta-me/issues/39
