Particularly session video releases? There are usually at least one or two sessions at any given conference I'm interested in, but even filtering for quality + relevance I'm up to about 20 different conferences now.
(For the curious, for me this is WWDC, I/O, BUILD, re:invent, multiple O'Reilly & Usenix conferences, QCon, DevOpsDays, @Scale, Edge, Monitorama, Rootconf, STAR, STPcon, CAST, ISSTA, TestBash, ASTQB Summit, and AgileTestDays.)
