I didn't see any documentation for the shortcode other than saying that you can give the option of the user ID. Is there more you can do with the shortcode? It would be nice if you could fill out all the information used in the box, like:
[social-bio name="Joe Smith" desc="Pioneer in short-code writing style." web="http://www.joesmith.com/" facebook="http://www.facebook.com/joesmith" twitter="http://twitter.com/joesmith"]
Something like that.
Also, I think it would be useful to be able to create a library of bios for use on the site. For example, if I have 5 guest authors, I create 5 bios with name, desc, social links, etc. and instead of saying [social-bio id=xxx] for social bios which draw their info from the user profile, you could say [social-bio lib=xxx] for a user drawn from the library of profiles.
If you could track all the articles linked to that author profile and be able to display the number of articles linked to that person, and list them when the user clicks on the button, even better.
