Export Google Reader notes to Instapaper (from better source than gist.github.com/1331457 )

google_reader_to_instapaper.rb

# Ruby script for exporting your Google Reader notes to Instapaper
# Uses the more reliable personal note Atom feed (other script I've seen uses a JSON file from Reader's export page, which often doesn't include links)
# Almost no failsafes, rate limit might be hit, so use at your own risk
# Outputs URLs and titles of notes that couldn't be submitted (shamelessly copied from gist.github.com/1331457 )
require 'rss'
require 'net/http'

## Config
notes_atom_feed = '' # log into Reader and save the feed from www.google.com/reader/atom/user/-/state/com.google/created?n=INSERT_NUMBER_OF_NOTES somewhere (n is item limit, I used something like 10000, just to be sure :P)
