So, just as I created this ThoughtStream (will from now on call it TS) and posted my first thought, I was confused. Where do I see that I am in the stream I just created? Turns out I wasn't :D I had to click on the TS in the sidebar first to post thoughts in that stream. Ooops.
Btw, now that I am in the right place, what the hell does a child stream do? I don't know yet, but I guess I will find out.
So this stream will also be about my experience and thoughts as a first time user. Maybe someone will find that helpful :)
