You probably haven't been exposed to it as much, but the term DevRel is as ubiquitous as DevOps, and any other buzzword from the last 10 years.

P.S.: Love all your OSS work!

do you feel the same about DevOps? or any other Dev* movement? is it somehow less legitimate because it's more touchy-feeley-people-y (its ok if it does, just have to be honest about it)?

people call themselves whatever they feel best describes their work, and work specializations develop over time in response to market demand.
