I'm a bit rusty now, but I used to make a lot of pasta and enjoyed teaching friends the wonders of making pasta. There's a learning curve as many other commenters mentioned, but once they "get it" it's magical.
I would organize parties where everyone would bring different ingredients and we'd make ravioli from the food we had. With noodles, some guests wouldn't understand why make the effort. But with custom ravioli, they would immediately understand it.
I feel like every company I've worked at talks about "exploring" a 401k match every year, but never makes it happen. After a merger or acquisition, they'll bring it up again but it never happens.
I thought that this would look for unique words rather than just cycle through all words. You should have a default ignore word list that includes things like el, en, de, etc etc.
To build an identity that's easier for your readers to remember and to start getting "credit" for SEO even if you're not actively optimizing keywords, etc. Why let substack reap all of the benefits?
I have a hobby blog that doesn't have to do with coding, but I post on substack. I enjoy the features on substack, but I would advise that you set up a custom domain if you post to substack.
