I have found it very difficult to read Digg for the past year or two, similar to how I can't read Slashdot anymore. The highest voted articles are not really that interesting, and you'd think that technical/scientific articles would be more interesting to a group of self-supposed "rationalists". Instead the site is morbidly political, with each "group" colonizing its own set of articles and never interacting.
I much prefer the level of conversation at HN and a handful of blogs.
If you feel that this is a mis-reading of the situation, I strongly recommend this thread:

Sort by the highest dugg comment. There are two that I noted at the top that were somewhat interesting, but the rest were just not useful; me too style comments to the extreme.
