Slashdot and StackOverflow give you more capabilities with a higher reputation. Slashdot likes to give moderator points to people with higher reputations, and to people who metamoderate frequently which is itself guarded by reputation. Your votes are recorded at StackOverflow with no real reputation, but they only count for or against a post if you yourself have a high enough score - I forget what they call your reputation/karma/whatever there.
