What a great idea! Ones server could serve the latest tweet, or current location, anything. I think there are a lot of risks, sanitizing input from “random” hosts mostly, there’s a chance that it could hurt your server when retrieved/stored or the client when it’s rendered. I wonder if you converted the curl results to a small gif, would that help or hurt the experience? One could run the conversion code in some sandbox, like FaaS.
Very neat! This reminds me of the finger protocol[0]<p>[0] - <a href="https://en.wikipedia.org/wiki/Finger_(protocol)" rel="nofollow">https://en.wikipedia.org/wiki/Finger_(protocol)</a>
