Kind of useless if you can't apply it to non-blog pages (tons of content exists outside of the traditional blog section). Unless it can go into the Page Settings > Advanced > Header Code Injection -- in which case...
That would be a game changer! I only recently built my site with SqSp and see that Commenting is only for blog pages (which I get) - but I have tons of content on non-blog Pages. The option they offer for those Pages is Disqus, which is doable but I'm curious what might be better. Thx!
We'll see if we can get some instructions up for the non blog pages!
We've updated the Squarespace instructions to include separate categories for each use case (adding comments to blogs, all pages, or a specific page).
Let me know if you run into any issues.
