There is an idea that it's flying around my mind and is that I would like to start a community or something similar writing my own blog or a newsletter...
The point is that I don't know how to start. I think that I don't have any interesting to talk about... and when I start to think on it, I don't consider that I have enough knowledge about any topic.
Do you know some cheatsheet to how to start doing it ?
How do you started yours?
