WebSub Kirby Plugin
My friend Daniel is running FeedCity, a feed reader I have been using for a couple of months now. (I’ll write a post about it sooner or later.)
When using FeedCity, you get all kinds of information about a feed, e.g., whether they are valid (many are not, strangely enough). Naturally I wanted all these icons to turn green/be active for my own feeds as well.

The most recent icon he added was WebSub.
I had heard about it, but never really looked into it. Thankfully Daniel puplished a post about how he implemented it on his site.
While working on it for my photo blog I thought, why not build it as a plugin from the start? So I did.
Here it is on GitHub: WebSub Plugin for Kirby
It is very straightforward and lightweight. I hope it is useful for some of you Kirby users out there.
Let me know if you find any issues – or if you have suggestions on how to improve on it.
