If you use Quora for a few weeks, you’ll be amazed at how good their feed is; while Facebook’s is likely familiar to more people, and does a serviceable and ever-improving job of showing you what you want regardless of when it was posted, Quora’s is ludicrously, shockingly good. I don’t worry about when I answer a question; if people follow me, are interested in the topics, and if the community thinks it’s good, it gets seen.
Tumblr rewards luck in post-times far too much; Quora rewards good content. Since the reduction of the arbitrary is a major aim of any system which seeks a “good,” Tumblr’s reliance on recency —which is, again, unrelated to quality— is a shame.
