@james84_ Hello ❤️

[Lars Jansen @oldstackjournal]

anyone know of any startup/saas launching platforms/directories that actually send traffic?

[Lars Jansen @oldstackjournal]

@daniel_dinoia Heya Daniel, how much can ppl make? Is is per view or something?

[Lars Jansen @oldstackjournal]

How the fuck do guys like Pieter @levelsio get anything done irl when they have 1000000 followers on @x ?!

[Lars Jansen @oldstackjournal]

wtf @X

[Lars Jansen @oldstackjournal]

So, confession time. Yesterday I setup a bunch of scheduled posts for X. Generated by ai to see how it would work. 8 ai posts, 1 real post. Can you guess which one was real? I wonder if this shit works for folks using proper tools? Or that know what they're doing?

[Lars Jansen @oldstackjournal]

@rambuilds_ I got 3 and I use them, does that count? 💪

[Lars Jansen @oldstackjournal]

@rethink_hub https://t.co/QpFYPP5Z3O baabaay!! Not up you’re alley but Leshgooo 💪

[Lars Jansen @oldstackjournal]

I keep coming back to this with small tools: the first version doesn’t need to be clever, but it does need to remember what happened. Draft IDs, sent states, receipts, logs, hashes. Boring shit beats clever guessing.

[Lars Jansen @oldstackjournal]

@lenatron33 Wow, that’s awesome 😮

[Lars Jansen @oldstackjournal]

@LuyunoworkLyu X all day 💪

A lot of product work is just trying to remove the sentence “oh, I thought it would…” from a user’s mouth.

[Daniel DiNoia @daniel_dinoia]

AI isn't the threat.

The threat is spending your one life doing what a machine already does for free.

Let it take the busywork.

You take the meaning.

Question for builders: what part of your product would you be slightly embarrassed to watch a stranger use for the first time?

That’s probably the bit to fix before the next “big” feature.

[Lars Jansen @oldstackjournal]

@SaidAitmbarek @X Looks awesome bro! How do you compete with all the other marketing offers? It’s such a tight market right now aye

[Lars Jansen @oldstackjournal]

Where do people get these copy/paste posts from? Is there an app or something? “looking to connect people on @X

if you’re into

- design
- building SaaS
- vibe coding
- AI tools
- building in public

say Hi or drop what you’re working on looking to follow active ones 👊”

[Lars Jansen @oldstackjournal]

Tiny social lesson from today: a useful post can be too tidy. Sometimes the rougher version works because people can see the actual thought happening, not just the conclusion.

[Lars Jansen @oldstackjournal]

Getting up at 4am to build before going to “work” is a pain in the ass🤮

[Lars Jansen @oldstackjournal]

@Ville_AI @X Yeah that’s what I reckon too

[Lars Jansen @oldstackjournal]

The more I use X, the more I think the best posts aren’t “content” at all. They’re just someone noticing a weird thing in public and saying it plainly before the thought gets worked out properly in their head :)
