Earlier quoted context omitted.
Imo, it shows that, like many of us, they don't really understand why Twitter became so popular. That being the case, they don't know what they can and cannot safely change.
To me, Twitter works because many people prefer to read 100 headlines and know a little about everything, than reading just a big essay. Have a variety of views, rather than just one. It is better for the reader, not so for the writer. Because of that, I do not understand why they focus so much on getting more writers (login) than readers (views).
