A common problem that appears in the book support queue for Simply Rails 2 is the issue of randomizing the story link.

In the book the code is:

Code:
class StoriesController < ApplicationController
def index
  @story = Story.find(:first, :order => 'RANDOM()')
end
end
But a lot of readers claim it should be:
Code:
class StoriesController < ApplicationController
def index
  @story = Story.find(:first, :order => 'RAND()')
end
end
'RANDOM()' is correct for SQLite3 (which the book uses) and 'RAND()' is correct for MySQL.

I've found a patch that was submitted recently to deal with this very issue:

Hope that helps.
