Whoops.. I'd already corrected it to be 20 "credits" instead of 10 "votes" but it never got made live. It's fixed now.
Also, not showing how many votes an item has or the top 10 was actually an important design decision. We don't want people to be biased into voting for things just because they're popular (or unpopular). We want independent thought!
And we plan to always try and implement the top 10 vote getting suggestions at any time. And as we implement a suggestion you voted on, you'll be notified and your credits will be freed up to vote on something new!
