Definitely a reasonable critique. What I didn't originally realize is that medium is more than blogging software. It promotes community among writers. You can also create an account and just follow people. (Yes, I know this is obvious to most)
I'm of the opinion that when you're developing an app that will be used regularly, it is justifiable to have an expensive initial load time, provided it allows for a better experience on following uses.
I understand there are purists out there that disagree with this, but... "Yeah, well, that's just like... their opinion man". There are always trade offs. You just have to make tradeoff decisions based upon the needs of your primary user base.
