In case somebody want's to give me feedback on my little blog, please do so: https://blog.jdstaerk.de
Your content is the kind of thing I'd search for using a search engine (and for those where I can judge the quality, it seems completely fine), but I don't see a reason to subscribe to your blog in some way. This kind of content (let's call it "tutorials") is only interesting to me if I currently face an issue, it's not something I read for fun or abstract learning. I subscribe to some blogs that have many tutorials, but their content is about a lot of varied things, and the value I get from these posts is discovery of new software or possibilities, not the tutorial aspect. Your blog is in a way more of a Knowledge Base than a blog to me, if that makes sense?
And yeah, probably it isn't a blog as per definition, but a Wordpress blog seems like an easy and fast way to setup a little website w/ tutorials :)
