I am on the opposite. What my friends like actually come out to be what I am probably going to like and I quite enjoy most of those likes. There are a few spammy one or useless crap, but overall the situation has been much better compare to, say, 2-3 years ago.

I think the way Facebook and Twitter present stream is inconvenient for users who have a lot of friends or following a lot of people. It is simply a long linear scan and it literally takes me ~10 mins to review when I am on at the end of the day, I just want to see what's going on in everyone's world, ya know. I don't think gallery style will work either. I don't know, but linear scan is just not working.
