alt Hacker NewsGenuinely curious where the best place online to do this is today.
Until recently my reflexive answer would have been Twitter, but [gestures vaguely at the state of it].
Would it be Substack, Bluesky, Mastodon, a personal blog, or somewhere else?
Maybe I'm overthinking it, but it's hard to know where to get started.

Against the grain here but I feel like it needs to be popularised. But have you considered trying to do it in person? Going to shared spaces, meetups, etc and talking to people.
It’s almost a dying practice but I feel it’s massively valuable in a way that can’t be replicated online.
I've found Mastodon to be the best platform for this in 2026. If you're working on something deeply technical, there is a good chance the upstream maintainers for whatever you're using and tons of academics in the field will be active on there. Except maybe for something LLM-related, that's still firmly in the Twittersphere, even in 2026.
I think the best way to do this today is having your own site, be it in the shape of a blog, digital garden or whatever and then syndicate, following POSSE[0], in case of wanting community or distribution.
Niche forums are still alive and well.
I run a blog and like to write about projects but it's hard to get feedback there unless you're willing to moderate comments. As a work around I started sharing build threads on places like garagejournal and you can get a lot of good feedback.
I think YouTube can be a good place for it, probably supplemented by a simple website.
Example, Pete's Garage.
Hackaday is still pretty cool if you're into technogadgets and the like
For sharing digital creations, X is still the #1 place to do it for visibility and discovery. I get a surprising amount of positive interactions there.
I like reddit, but feel the moderation model is too skewed towards censorship. I created an informational post recently on a niche subreddit and it seemed well received, but then was deleted by a mod with no explanation.
I crosspost to LinkedIn, Twitter, Bluesky and Mastodon. LinkedIn is the most effective.
I also blog, but POSSE is not as good as it could be.
Mastodon and blog both sound good to me. For some, they could alternatively use twitch or youtube.
Isn't twitch or YouTube live the obvious sort of way?
I would begrudgingly suggest LinkedIn. I have seen a bunch of professors doing it there successfully. There they also promote their Substack which LinkedIn allows. I remember Elon had banned Substack on X at one point.
It's probably still Twitter.
With the real time translations that they just introduced where people are interacting in all different languages now, it's the best it's ever been. The conversations that people are getting to have across Japan, France, Spain, South Korea, etc are really incredible.
I don't know how publicly you mean, but I do this on the maker community I'm a part of (shout out to our general maker newsletter, sign up at https://www.themakery.cc/ for fun links).
I also do something like it on my website, but that's writeups of the finished product. The community gets to see the raw state of what I'm making, throughout the process.
Does substack have a built in community like that? I thought you really needed to get people there or use it for the newsletter feature.
> but [gestures vaguely at the state of it]
Everyone wants to gesture vaguely at the state of it but it's still by far the best place. Just use the site the way you want to use it, post the way you wish others posted, and mute stuff you don't like aggressively.
