The "chalkboardy" up/down arrows, star, etc. are kinda weird... any chance you could just use plain up/down arrows like on most other stackexchange sites?
From the FAQ:
Why does this site look so “sketchy”?
The site is still in the process of being defined and constructed, so a temporary placeholder design will be used until the site is fully formed and ready to leave beta. Once the site is no longer beta it will have a logo, domain, and design of the community's choice -- see our meta-discussion site if you have ideas or feedback!
