I have 2 features that I think would be beneficial for social author profiles:
1) Manual integration of other networks an author may be participating in. For example, if I view a profile that has tweet leading me to an author’s blog, youtube page, facebook page etc. I’d like to be manually add those into a profile so that I can see all posts/comments across all active platforms.
2) Pull in interactions with an author that are not made natively in moderation. Within moderation stream you can see replies made an author, but they are not visible in the author profile.
