Currently, the Model Share seems to be mainly used to receive Community Points. Many shares from the same people, pretty project-specific things without much explanation.
The idea behind it is very good. It might be good to add categories, patterns, connect it to modules and widgets in the app store and to provide some more guidelines on how to add value to this platform.
I agree with Bart.
I would also like 'private' shares, where a model share is only visible with a direct link, and not to the public.
