Product Management: The Good, the Hard, and How to Know If It's Right for You What I like most about the job, what makes me sometimes want to take a break, and how to choose between PM and EM roles.

An engineer recently sent me some questions about the #productmanagement role. I took a long time to respond because I saw it as a great opportunity to reflect on the role and what it means to me. I decided to share my answers here, in case itโ€™s useful for anyone else!

MCP Is RSS for AI: More Use Cases for Model Context Protocol MCP's simplicity means that, like RSS autodiscovery and OpenSearch, it can catch on quickly and deliver powerful leverage for developers.

โ€œMCP Is RSS for AIโ€ is a good analogy, but my analogy would be that MCP is like โ€œDynamic FAQsโ€, with the difference being that any question you ask could be considered โ€œfrequentโ€ enough to be vetted and correct.

Iโ€™ve been completely nerdswiped by MCP servers... hereโ€™s one I made for Lastfm. Use Claude Desktop to ask questions about your personal listening data. Try it out, let me know what I should add!

@richeholmes.bsky.social Hey, any chance youโ€™ll ever move off Substack? I stopped giving them money, but will happily become a paid subscriber if you move to something like @ghost.org or @buttondown.com.

Love this take on the โ€œ10x engineerโ€. Ubuntu (the African principle, not the OS) strikes againโ€ฆ โ€œI am because you are.โ€

โ€œIt doesnโ€™t matter how fast an individual engineer can write software. What matters is how fast the team can collectively write, test, [โ€ฆ] and revise the software that they own.โ€

The history of album art I speak and write about design, front-end code, leadership, and (occasionally) math.

Any celebration of Reid Miles gets an automatic boost from me. Legend.

โ€œMiles fulfilled the Blue Note manifesto. His album covers pushed the envelope of graphic design just as the artists on the records inside continued to break new ground in jazz.โ€

Every once in a while a preorder shows up before release date and itโ€™s always such a wonderful thing when that happens.

Mdou Moctarโ€™s band made a 4-track EP. It comes out on Friday but it showed up today and this thing goes so hard. Itโ€™s like post-punk desert blues.

I Learned to Listen From My Dad He taught me a crucial survival skill when he passed down his rockโ€™nโ€™roll fandom.

โ€œThe single-most important thing he gave me, besides unconditional love, was modeling how to use music in my life.โ€œ

Which Movies Have "Aged Poorly"? A Statistical Analysis Which films have not stood the test of time?

Interesting data on which movies aged poorly (and well), but itโ€™s the genre data that stood out to me.

โ€œAccording to our rating-change data, horror movies age notably well, while comedy and drama see a marked decline in appraisal over time.โ€

Huh? The valuable role of interjections Utterances like um, wow and mm-hmm arenโ€™t garbage โ€” they keep conversations flowing

I love this deep-dive on the little interjections we use in everyday speech. One example:

โ€œOther interjections serve as โ€˜continuers,โ€™ such as โ€˜mm-hmmโ€™โ€”signals that the speaker should keep going. Because โ€˜mm-hmmโ€™ is made with a closed mouth, itโ€™s clear that the signaler does not intend to speak.โ€

This is a good @harper.lol primer on how to โ€œbrainstorm a spec, then plan a plan, then execute using LLM codegen.โ€ If you have an idea for a product this is such a great way to get a working prototype out there.

How Do Music Listening Habits Change With Age? A Statistical Analysis How does music listening change as we grow older?

This tracks (lol) and seems obvious, but the data is fun.

โ€œYounger listeners tend to exhibit a โ€˜discovery mindset,โ€™ actively seeking novelty. Older listeners may approach streaming from a โ€˜maintenance mindset,โ€™ knowing what they want and using a given platform to reinforce established preferences.โ€

Middle-earth disinfo campaigns Denethor, Palantรญrs, and propaganda in J.R.R. Tolkien's Return of the King

When @andrewliptak.com writes about Lord of the Rings, I pay attention. This is one if his best, yโ€™all.

โ€œA critical theme throughout Tolkienโ€™s work is the decline of a once-great people, with weak men failing to live up to the lives and stories of their predecessors.โ€

Hah! Too real. My wife and I always joke (?) that if we ever get divorced it would be over โ€œirreconcilable differences about music.โ€

Anyway, I mostly ran it through my NAD M33, but also gave it a whirl through the office setup, which is the Simaudio Moon 240i. Both were amazing.

I ordered their CD player and it surprised me with how much better than streaming it sounded. Ultimately it had some mechanical issues so I had to send it back. But I do follow them closely, and I love their copy so much.

The Ghosts in the Machine, by Liz Pelly Spotifyโ€™s plot against musicians

I finally had a chance to make my way through this well-researched Spotify exposรฉ, and dang itโ€™s infuriating.

โ€œA model in which the imperative is simply to keep listeners around, whether theyโ€™re paying attention or not, distorts our very understanding of musicโ€™s purpose.โ€

Regarding "missed" and "slipped" deadlines One of the issues with quarterly planning cycles and committing to due dates on that cadence is that teams are often asked to commit to dates before they have figured out all the unknowns.

I wrote a little bit about the unhelpful language we sometimes use when teams "slip" on deadlines.
