I follow a few individuals through RSS:
There are a bunch more on my rss list, but I can't remember their last post, so I'll skip them.
Besides that I follow feeds not related to individual people like the top questions from softwareengineering stackexchange (you can follow those with rss), some weekly newsletters, the IntelliJ blog, lambda the ultimate, programming digest...
I follow more people on Twitter, but I don't really read actively Twitter actively anymore, it's too much politics and noise.
And here on Hashnode you can see who I follow - not many.
