This is not a "something is broken post" but it is something for users to be aware of:
If users have a plugin which takes an action based on adding custom content types, TablePress has a custom post type called
tablepress_table be aware.
If users of Table Press are also using the plugin Add Link to Facebook (with over 1 million downloads) and they convert to TablePress from WP-Table Reloaded then when the conversion takes place the newly registered custom content types in TablePress will get automatically posted to the users Facebook Location. there is a place in the Add Link to FaceBook plugin to stop some featured of Add Link to FaceBook from applying to custom Content types, but I am unsure at this time if it applies on import or newly created tables (untested). - This is not an endorsement of ALtFb, just it is really popular and I do use it....
