Interdependency: Each post in a sequence requires understanding of the previous posts in that sequence, and sometimes posts from earlier sequences. As well as being a source of intimidating and annoying tab explosions, this exacerbates the problem of length. It’s hard to read the sequences except going through large chunks systematically, so they can’t be broken up and read in a person’s spare time.
Couldn’t one just start from the beginning?
That’s how I did it, and it worked pretty well for me.
That said, different people are different.
