I wouldn't say FB is better. On Twitter you read people's philiosophical notions. On FB, you get to see what they ate for breakfast, every pub they visit, every article they read (but you can't read it unless you sign up through FB), every game they play - often much of it automated rather than typed by them, so it generates vast amounts of noise to signal.
..... Twitter: A more annoying version of FB--- I never bother with twitter, since every TwitI have ever read is pointless. Seriously, why do I want to know every action or philosophic notion, some one has ?
Years ago people would criticise places like Livejournal as places where people posted about what they ate for breakfast. I don't think they did, but still - if today, I saw "Ate breakfast [Get the new Breakfast App so people see when you have breakfast!]", it would be one of the more interesting things on FB.
Oh, and in response to the OP, FB already has a system where it decides only to show you the most "important" things. Whether you like it or not.
