I start to type something and then the conversation has already moved on by the time I finish my thought.
Happens to me all the time. I'm pretty awful at collecting my thoughts into something coherent when it comes to saying or typing it. The faster pace actually sort of helps in some odd way. Not as much time to over think it, I guess.
I'd say it helps increasing your abilities to quickly build sentences

No idea how it is in otehr countries, but over here teachers are strictly told what to teach their students. And the way it's build up there's not much to teach free thinking to the students.
