Not sure if this is the right place to ask, but why does Bluesky feel so much faster to load and interact with compared to X? On the surface, both have similar interfaces and equally rich content, yet Bluesky consistently feels snappier and more responsive, even though it’s the newer platform.

Newer is generally faster, hasn't had time to accumulate cludges and dead ends from years of evolution. The bigger factor though I would imagine is not having 100 tons of analytics tracking everything.

No idea, but Twitter is functionally un-usable if you're not logged in.

Could be from lower usage.

Iiirc, Twitter uses some mongrel version of React Native on the web. That's why you get the 3 seconds long loading thingie whenever you open a new tab.

Having a fraction the activity probably helps.
