I like the plugin, however one thing that has always bugged me is the false advertising by the plugin author.
On the plugin description page, he specifies support for Schema, but that is only available in the paid version. I'm sure it was intentional, as he mentions in the description:
'The Pro Version support star ratings into your BuddyPress activity updates and comments, BP's bbPress forum posts ratings.',
while the Schema support is mentioned in the main description, in between features that are available for free.
He is intentionally trying to mislead people into installing the plugin, which while a smart marketing tactic, is unethical.
