The searches in different places for the same things reenforces what librarians probably know - it does make a difference what you search and where you search.

As someone who does not spend a great deal of time messing around on the computer - at least time that isn't job related - or watch much news, I find I understand a bit better the scope of interest in current news and entertainment.

However, when I went to the most popular blogs, the scope of topics got broader. The tech-related and more culture-related topics seem to have more lasting power.
