I cannot put into words how profoundly stupid this “feature” is. AOL and Geocities pages were genuinely more user friendly. Whoever added it, refreshed the page and said “yeah, this works well” and left it in should be fired! …out of a cannon and into the Sun!
It was never exactly a feature, it was to do with how websockets handled new posts. They’re movinig away from websockets in 0.18 so it won’t be a thing anymore.
And it was never useful, by any sane argument. NEVER (purposefully) spontaneously move text out from underneath a user’s eyes!
