Substack versus Twitter:

You can almost use Substack like Twitter:

"Substack has leaned into social features lately, so it can feel a bit like Twitter/X. But there are some key differences:

• Core purpose:

  • Substack = publishing platform (mainly long-form newsletters, essays, and podcasts).

  • Twitter/X = microblogging platform (short, fast, viral posts).

• Format:

  • Substack posts are usually long-form or at least essay-style. You can comment, “like,” or “restack” (similar to retweeting).

  • Twitter is centered on short bursts (280/25,000 characters max), fast replies, threads.

• Audience relationship:

  • On Substack, people subscribe (email + app). It’s about building a direct reader–writer connection.

  • On Twitter, people follow, but you don’t own the connection (if the platform dies, so does your audience).

• Monetization:

  • Substack has built-in paid subscriptions. Writers earn directly from readers.

  • Twitter has tips, subscriptions, ad revenue share, but it’s less central.

• Community vibe:

  • Substack is slower, more thoughtful, often niche communities.

  • Twitter is real-time, chaotic, broader reach but noisier.

In short:
Substack mimics Twitter’s social layer (restacks, likes, discovery), but the backbone is still publishing + email lists, not short-form chatter. Twitter is about speed and virality; Substack is about depth and loyalty."

Probably the average quality of stacks is higher than the average quality of tweets. The community is smaller. It feels more niche.
