I am the author and used the phrase "Code review is a pretty good idea, in general" in the opening very specifically, because it used be one of the selling points listed on the Phabricator homepage. :) I miss it.

Also, Evan Priestley still uses the https://secure.phabricator.com instance to occasionally post life updates, so I check in on it.
Last I checked he was learning about PCB design and printing. I think he wanted to learn how to actually physically manufacture his own boards (e.g. etching your own conductive copper layers) and then he posted some update like "I'm not sure I'll go down this route, because it turns out you can send your design to PCBWay, and it will come back within 5 days, because there is a magical PCB Faucet somewhere in Shenzen apparently."
