I have a suggestion for Twitter. It would be nice that there would be such option as twitter account grouping. Its like when you can group who are frineds, official sites e.t.c. It would be easier to read all tweets with filtering only what your friends have wrote or some other type of group, like news. I think this feature will only make twitter more comfortable and easier to follow others.
