I really like the options from this software, social comments and posting are really good.
2 suggestions comes in mind for comments:
1. When pulling comments from social, also give the option to reply back to the same posting #id
2. Give the option to remove fields from comments, eg. I wanted to disallow "website" from the comment fields as it was used for spamming only, had to modify the code a bit...
Anyway a fantastic piece of plugin!
