Show buttons in RSS feed

Hi

I’d like to use the buttons at the bottom of each post in RSS feed.

How can I do that?

I’ve added <?php echo really_simple_share_publish($link=”, $title=”) ?> at the end of each post in RSS but it doesn’t seem to work.
I don’t think it’s an accurate way to achieve that goal.

May be you could add this feature to the plugin?
