For instance, Burton Baton is a relatively unique beer yet it has a surprising amount of recommendations associated with it while many other beers have few or none.
Also, how were the beers picked out? Its a relatively small set and its not based on popularity - which would give people a better reference point. And if its based on rating, I'm surprised at some of the beers not on the list.
I'd say it's to the site's credit that it doesn't include Budweiser and other cheap mass-produced domestic beers. The site is clearly designed with beer enthusiasts (or at least budding beer enthusiasts) in mind.
Interesting! The "Choose your preferred beer strength..." by lightness to darkness doesn't make much sense to me. Stouts (not including doubles and imperials) are usually much lower ABV (4%-6%) than IPAs and imperial IPA (6%-12%). I suggest changing to something like "Choose your preferred beer style...".
