Google's IR properties are so good, that I think it has changed what I remember and what I do not. I'm terrible with names to begin with but queries like "movie with guy who starved because he ate poison berries and is an idiot" return the correct result on the first SERP.
That's great. And, I'm *aware of* my cognitive limitations and what I want when I issue a query. Social networking is very different from that. It solves temporal attention issues. (I don't really have a point here. This is a note.)
