I used to subscribe and ready many blogs about a decade ago - all in Google Reader. When that died, so did my blog reading habits, and I never went back to reading a specific blog on a regular basis.
Nowadays, I only visit blog site when they come up as a Google search result. Even then, single visit to get the info I want (usually a programming or business related thing) then I close the tab and never go back to that site. I cannot remember ever bookmarking a blog home page for later reference in the past few years.
No slight against those blogs - usually brilliant content written by smart people. It is just that I don't have the time these days to stop and read article after article on one particular site. We are just so flooded with information these days that I see it akin to fishing in the ocean. It is no longer worth spending the energy to just try and catch particular sort of fish - I just throw the line in and see what comes up and make do with that.
As an aside, it will be interesting research to see if the death of Google Reader had an impact on visitor stickiness to blog sites. I know in my case, it completely changed the way I consume blog content altogether - I wonder if it was the same to others?
