Reddit's Contributor Program could earn you real money for your Reddit karma [Android Authority]. This mirror's Twitter's experiment to pay select top contributors [Washington Post].

Implementing changes on announcement (or lack thereof), with no warning or transition period, is entirely Elon-esque as well.
