Do links have different values if they come from .gov or .edu websites

Matt answers this question on video

– No. They (.gov /edu ) are treated the same.

It is just that .gov and .edu tend to have higher PageRank because more people and more reputable people link to them.

A link from a .gov carries no more weight than any other.
