- Since June 23rd, 2015 facebook.com deprecated the RSS feed endpoint for public pages:
- https://developers.facebook.com/docs/apps/changelog#v2_3_90_day_deprecations
-
- They suggest to use the Graph API but they fail to mention that it does not
- work anymore without authentication, so it cannot be considered an
- _equivalent_ solution.
-
- Luckily we've got Tweeper!
