Combining several blogs into one feed sounds like a job for a developer, and Susan Bachelder wrote the walkthrough that makes it a job for anybody. She explains what a feed actually is, then takes you step by step through a free tool that merges a whole team's writing into a single stream you can share or read in one place. Those posts are the most practical thing here by a distance.
She also explains, calmly and without mystique, how one social network decides whose posts anybody sees, and what a change to that system meant for people publishing on it.
The personal writing comes from a harder place. She lives with chronic pain, writes about looking for the lesson inside a struggle without pretending the struggle is a gift, and describes single motherhood as her proudest work rather than her hardest.
Forty three posts. Take the feed tutorials if you run a team, and the struggle posts if you are in one.
