Here are my slides from my WordCamp Lancaster 2019 talk on “Advice for New WordPress Developers”. You can also see them on SlideShare.
Chris Diehl and I presented a pair of presentations at the WP Philly meetup this evening on the new Gutenberg editor. Here are my slides; you may also find them on SlideShare.
Edited to add: Updated one of the slides and reuploaded presentation.
Last month I shared my suggestions and war stories with WP Philly users about selecting plugins, and even as I was standing there talking I realized I could easily put together a companion presentation offering advice to the WordPress developers whose plugins we were considering.
