Erlewine hired a database engineer, Vladimir Bogdanov, to design the All Music Guide framework, and recruited his nephew, writer Stephen Thomas Erlewine, to develop editorial content. In 1993, Chris Woodstra joined the staff as an engineer. A "record geek" who had written for alternative weeklies and fanzines, his main qualification was an "encyclopedic knowledge of music". 1,400 subgenres of music were created, a feature which became central to the site's utility. In a 2016 article in "Tedium", Ernie Smith wrote: "AllMusic may have been one of most ambitious sites of the early-internet era—and it’s one that is fundamental to our understanding of pop culture. Because, the thing is, it doesn’t just track reviews or albums. It tracks styles, genres, and subgenres, along with the tone of the music and the platforms on which the music is sold. It then connects that data together, in a way that can intelligently tell you about an entire type of music, whether a massive genre like classical, or a tiny one like sadcore."
