Typo, the "like" system was introduced to address these concerns. It's a public voting system so you can see who likes your snippet. Also, likes are what bump snippets to the front page, not the score. We've even lessened the real estate for the score on the snippet listing page because of these concerns. It's no longer a large number but a small font that requires a little searching to seek out. The "likes" are much more prominent and will be the ongoing currency of the site.
