Ask HN: Has anyone else skipped El Capitan entirely?

Have used Macs for 25 years, and I just realized that El Capitan will be the first major OS version I've ever skipped. I recall seeing that the initial upgrade numbers were low, but I didn't suspect at the time that I might end up skipping the version altogether. Anybody else in the same boat? Would also be interested to know what I'm missing out on, if there's anything cool.
