Thanks for the reply!

I'm glad the guide looks useful for you. Finding the right quote length is tricky. Basically the idea is to stimulate discussion here and give people enough information so that they can decide whether or not they want to click through to the source link to learn more.

I can understand your hesitance about commenting in English. I've been trying to learn German, but I have the same hesitation about joining in German language discussions here. I guess the best way to learn is to force oneself to participate, but it's definitely not easy to do that. Eventually, it might be good to have "Steem Links" communities in multiple languages, when there are enough people and curators here to support it.
