This gives me a little of my faith in human nature back. Including Twitter in SERPs without some sort of moderation (i.e. choosing whose Tweets to monitor, even if this is done algorithmically) is like those annoying vox pops on the news.
I don't watch the news to find out what some random in the street thinks about an issue - I want to see what leaders/politicians/campaigners - in other words informed professionals - think about an issue.
If I wanted noise / buzz / chatter I'd go to a social (search) site, not a search engine.
