I was recently writing a post about making an app with React. The app is quite small, therefore I was surprised that it took me 3 evenings (approx. 2-3 hours each) to write the process up and one evening for proofreading/fixes).

I was wondering how long on average does it take people to write a post?

A follow up question would be: if you write about building an app/webpage/etc, do you

1. Build it while writing the post
2. Build the app first and then write the process up
3. Do not bother with building the app at all and checking that the code actually works :D
