http://popurls.com/ - There's a Technology section at the bottom with lots of different tech news sites. Some may fit what you are looking for.

http://alltop.com/ is surprisingly good. Again, not positive if it will fit exactly what you are looking for, but I found http://python.alltop.com/ to be useful.

Well, if there are only 3 technology sites out there which allow user voting and comments (Reddit, Dzone and Digg) maybe it's time for another one?

Those tech news sites from Popurls don't allow user voting (just comments), as far as I know. The same for Alltop.

It's been two days, so I'm not sure if this will be seen by the OP, but I was really trying to make the point that even though popurls/alltop may not have the features you are looking for, you may find that some of the sources that feed these aggregators may have those features. You can use popurls/alltop to find more sites that have the features you're looking for.
