Someone else phrased it well. Pithy replies are in vogue as they require you to put less of yourself out there and take less of others in. I miss the meandering crunchy streams of thought as well, but most of the current internet is harsh to them. Succinct affirmations or bust, except on Tumblr, one of the last vestiges of the old internet. 4chan lost them just around when stormfront moved in.
