Wow, that's a great pearltrees.com replacement!

Can I use it personally/privately already?

Can I selfhost it?

Can you make it available on GitHub?

Can you make the CTA-Button (call-to-action) more visible? I haven't edited links, but would you consider making editing/moderation similar/better than wikipedia?

What about import/export, that would be a killer feature and allow you to keep your site closed-source, but make FOSS clients that asynchronously add/receive benefit.
