Nice to hear you are enjoying the series! (It turns out to be a series.) It also feels really good to have finally found a form again where I can cycle between writing code and writing blog posts about the code.
Looking forward to read your article && yaay it worked!
Edit: lol, next topic really is Webmentions: I had to manually send this one because I am certainly not parsing HTML with regex (I would never) and your
rel has no quotes around it.
