That would be really great! It's always a pity when this happens:
- I read a great article.
- I have a look at the rest of the blog, seeing more interesting articles.
- I see that the posting frequency is low. [1]
- I want to add it to my QuiteRSS reader, but there is no Atom/RSS feed.
[1] Which is actually a very good sign! Daily posters are inevitably posting mostly crap, and I'm too tired of such blogs to pick out the cherries. I prefer authors who publish only their cherries in the first place, or at least provide a "cherry-only" feed.
There are several services out there that will create an RSS feed out of any web page. They do this by periodically scraping the page's contents for you. https://feedity.com/ is pretty good; there are others.
