Interesting, Based on my own discussions with friends and my own experience, it's considered strictly annoying and done likely to save bandwidth or something. Can you explain what you like about it?
I like knowing which tweets I've read. If it says that there are new tweets, can click it and see the new tweets appear. If they just appeared on the feed, I wouldn't know as easily which tweets are new. Does that make sense? I guess I just like being able to load the new tweets on-demand.
