Too many! I read almost none :| I am trying to do a better job of it. One thing I have done is just put the links to what I think are good eng blogs into a simple page on Nuclino, with the idea of periodically going back and checking them out manually. This has been progress, but precious little.
One thing I wish in this regard is that Substack didn't have the paradigm of "a hosting platform for independent newsletters/blogs"--I want one email per day summarizing posts in the past 24 hr from Substacks to which I am subscribed, I don't want every individual blog to spam my inbox at random times.
