What Hacker News says?
The proper way to think of Medium is as "Long Form Twitter" - that it's not where you should primarily post your long treatise about XYZ, but that it's a secondary platform for promoting it, interacting with the audience there, etc. OPs article describes the first landing UX - which is definitely bad, but not what a habitual Medium reader sees. I wrote this much bigger posts about it here [1], but the TL;DR is that…

HN discussionThe general term for what Baremetrics is doing is called "content syndication" which is the fancy buzzword term for putting all your content on your own blog/domain first and then copying/importing it to other sites. What makes Google not flip out and de-rank your content for duplication is two things: 1. There is a specific rel=canonical tag that sites can add into their headers pointing at the URL of the source ar…

HN discussionI tried to launch a SaaS to do automated QA of email sends (check them for broken links before sending, mis-sized images, etc.) which was a big failure as the pain wasn't strong enough. But to try and promote it I created a free automated email subject line checker which people loved -> https://sendcheckit.com A couple years in and we've checked around 5 million subject lines for people. There's an embed API that I…

HN discussionI worry that too often startups and developers write off content marketing as "more 500 word fluff blog posts". As devs we have a tremendous advantage in that we can build tools as a form of "content engineering" that easily have 10 to a 100x the impact of just writing articles. An article that gives advice and a tool that actually helps you put that advice into practice while seemingly related - in terms of executi…

HN discussionIf there's one consistent issue that plagues startups, consultants, and even large established business it's marketing. And that whole thread touches on a subject that I wish would get more traction here on HN: content engineering. Content Engineering (building tools and useful online software projects) is an incredibly effective way to build an audience and awareness by helping people instead of writing yet another…

on “Attracting high-paying clients to design and development agencies”Slightly different slice into this a very similar situation (local vs OpenRouter AI inference). But in _every_ metric other than privacy it was better to run via OpenRouter than a local model, and not by a small amount. Direct link to the comparison charts: https://sendcheckit.com/blog/ai-powered-subject-line-alterna...

on “Apple Silicon costs more than OpenRouter”I ran a fairly large production test of this and on _every_ measure except for privacy it was worse than a free tier server hosted LLM. Not happy about that as I would like to see more local models but that's the current state of things. https://sendcheckit.com/blog/ai-powered-subject-line-alterna...

on “Google Chrome silently installs a 4 GB AI model on your device without consent”Fwiw - I did a fairly large comparison of Gemini Nano (the in browser ai model) vs a comparable free hosted model of Gemma (from OpenRouter) and the hosted model absolutely trashed the local model on every aspect of speed, reliability, availability, etc. [1] I'm not particularly happy about that outcome as I wish we had more locally run AI models for reasons of privacy and efficiency, so this is more just a warning…

on “The Prompt API”FWIW - I did a real world experiment pitting the built in Gemini Nano vs a free equivalent from OpenRouter (server call) and the free+server side was better in literally every performance metric. That's not to say that the in browser isn't valuable for privacy+offline, just that the standard case currently is pretty rough. https://sendcheckit.com/blog/ai-powered-subject-line-alterna...

on “Show HN: Gemma Gem – AI model embedded in a browser – no API keys, no cloud”I recently dug into this as I was trying to benchmark the possibility of using Gemini Nano (Chrome's built in AI model) vs a server side solution for a sideproject. Nano's stored in localstorage with shared access across sites (because Google), so users only need to download it once. Which I don't think is the case with Mistral, etc. There's some other production stats around adoption, availability and performance t…
