Of course I see a lot of people with large accounts that vote at 2% or 3% giving people something like a $0.01 or $0.02 cent vote even though the dust threshold is $0.03.... and that's annoying too. I guess in a case like that it would be okay to upvote yourself a little bit just to bring it up to $0.03.
Or just use @dustsweeper to avoid that issue.
Dust sweeper is a great option.
