I'm sure you've thought about this, but I don't see it from the landing page:

What does a person with a project get out of sharing?

Or looking at it from the other side, what is the compelling reason this site will attract people looking for others' side projects?

It seemed like the main CTA was to sign up for a newsletter about marketing ideas. What's the connection between side projects and marketing newsletter?

As someone with a side project, genuinely interested :-).

Submitted my litte weather API projec: https://open-meteo.com

Thanks for the free promotion opportunity!

I like how you choose to use your own domain ( subdomaining ) for this project. Do you have any story behind this choice? I think this is most underrated one but people realise the brand power from it. I'm digging it.

Submitted my project!

A small bit of unsolicited feedback: you should make it more obvious what people get out of it before listing the price (at the end of the wizard). I'm not sure if I overlooked it, but I didn't see something like how many people will likely see it or if there's a newsletter with x subscribers and an opening rate of xx% which you see on similar sites.

Please don’t require a twitter handle. I don’t use Twitter. Thank you.

This is interesting, what's the visibility like on the platform? Do you have any numbers from the projects already listed there?

That's fun. Has that no-code website vibe. This was a side hustle until itself perhaps?

Why do we need another one?

This looks nice.
