"Stack gems" is ambiguous: it could mean Stack Gems, a review site for developer tools 1, or Ruby gems in a stack. Stack Gems is the named product, so it leads, but the request does not say which platform or language the gems are for, so a question is asked.
A question back: Do you mean Ruby gems (RubyGems) or the Stack Gems review site, and which language or platform is your stack built on?
