However, it seems like all of the bash-to-zsh posts boil down to better autocompletion and oh-my-zsh. I haven't really seen anything fresh in quite some time. This is something that I do not understand. Does the author think he is saying something that hasn't been said, or is the hope that if we keep saying the same thing over and over that we can get more people to try zsh? I really can't say.
Also, I recommend not using oh-my-zsh if you are a beginner. Rather, I recommend that you start with a blank slate and read the documentation. This is the only way to get the exact configuration you want. If you don't really care about your shell that much, then why are you switching in the first place? Alternatively, you might try using the "recommended" config offered on first run (I can confirm that the default config on Debian is a good start and will work for most people). Then go through that config while reading the Zsh User Guide[1] and tweak it to your liking. It is my opinion that oh-my-zsh ultimately stops people from reading documentation and offers an incentive (ease of use) for using code that may not be understood (when it probably should be). However, a lot of people seem to like it. Perhaps I am missing something.
My intent is not to discourage this author specifically, but rather to call into question the underlying motivation and behind and utility of all posts of this type.
