http://apiwiki.twitter.com/Twitter-REST-API-Method%3A-favorites doesn't mention any limits to the "page" parameter.
Through trial and error I figured out that curl --location --referer ";auto" -D - -s --netrc 'http://twitter.com/favorites.xml?page=175' was too much but curl --location --referer ";auto" -D - -s --netrc 'http://twitter.com/favorites.xml?page=174' seems to work. At 20 per page, that works out to 3,480. TjL
