No way yet.

But you can do it on own website:

elgg_list_entities_from_annotations(array(
    'annotation_owner_guid' => elgg_get_page_owner_guid(),
    'annotation_name' => 'likes',
));

the liked_content plugin is worth a look

@ura soul Yepp. I forgot about it ;)

@RvR - IIf it is not too difficult can someone install/add that code in elgg.org please? Thanks.
