Slashdot is what it always was. They have maintained their identity in spite of all the new trends, and they will continue to maintain their audience. Digg, Reddit, HN.News are different from Slashdot.
Then again, how much traffic I really received I'll never know. If you're doing more than 50 connections/sec, they shut down your account so their other clients "don't suffer".
I promptly moved. And I don't recommend them.
