I even consume HN via RSS: I have separate RSS feeds for items that reach 50, 250 and 1000 points, respectively.
I'm working on increasing subscriptions on my blog - do you frequently see the "Subscribe on Feedly" buttons, and if so do you use them? Or are they not useful?
I don't think I'd use a "subscribe on feedly" button, typically I just copy and paste the URL into feedly and it automatically scrapes the RSS feed, if it exists. Sometimes I manually copy the RSS link directly from the website, when exposed.
I know that some blogs put their full articles in the RSS feed, so you can just read it directly in your RSS viewer, email notification, etc. I've tried doing this too but since my blog is 100% bespoke PHP (i.e. it's not WordPress or some other big platform), it's not easy to do. When I write an article, I'm literally writing raw HTML with some included PHP functions to stick the navbar and footer on. It's not easy to get this into an RSS feed as you can imagine...
