I completely agree with Jacob. The quality of voting is very important. We'd love experts adjudicating over every question and answer but that's a far cry from people just casting votes on everything they see, especially if they don't understand the problem or answer. That would devalue the site and votes as a whole.
If you want to help with votes,
- Vote for the things that help you (or against those that don't)
- Vote on posts in your areas of expertise.
- Follow the tags that interest you so you find yourself looking at the right posts(for you) more of the time.
