Friendly suggestions

Ok, so I saw @datachomp open this project up.  I took a look, and I thought I'd throw in a few suggestions.  

I did this while watching tv, so don't trust everything... my attention was spread out.  

Look at me, I'm a fancy Rails developer, look at my fancy routing with the scopes and the Ruby blocks...

Notice how that :all presence check can be replaced with a concrete variable that's set in params when the route is bound.  This trick can be very, very handy...

but you have to use the old kind of routing with the string and the hash sign like "suggestion#index".  My ```viewing: :recent``` stuff doesn't work with the fancy Rails routing, but hey... we should be complying with the new ways, anyway?
