If throttled wait 1s

[twodayslate]

See https://github.com/lobsters/lobsters/blob/master/config/initializers/rack_attack.rb

I've been getting throttled recently (probably due to #30) and a 1s+ wait may be good.

Might be good to have a static story fetcher with a queue of stories to load. Once the story is visible then that one goes to the front of the queue. This enables preloading without having two many requests at once.

Perhaps have an advance option to specify your story cache limit.
