I have started paying attention to this: I tend to vote up people who have <i>done something</i>, whether it's a company, a cool hack, or something along those lines.  If a "blah blah" post like the Google one has already got a lot of votes, I'll tend not to vote for it (especially since there's no classification filter or anything like that), even if I like it.<p>I also tend not to vote for stuff if it's already in the top 5 spots - what's the point?  I'd rather let other things bubble up.
