Over on Daring Fireball, John Gruber has some true words to say about those pesky floating sharing bars (or “dickbars” like he calls them) used by Medium and others.
A website should not fight the browser. Let the browser provide the chrome, and simply provide the content. Web developers know this is right — these dickbars are being rammed down their throats by SEO experts. The SEO folks are the same dopes who came up with the genius strategy of requiring 5-10 megabytes of privacy-intrusive CPU-intensive JavaScript on every page load that slows down websites. Now they come to their teams and say, “Our pages are too slow — we gotta move to AMP so our pages load fast.”
