Basically, I have a database with some people, and one of their data is a list of comments made by each other. So I need to make a kind of “profile page” with a carousel of all comments received by the profile owner.
What would be the best way to do this?
Depends on how “fancy” you want it 
Does it need to do a whooshy rotate?
For a simple one you can run a workflow on the page every x seconds. Your text would be in a group, and the group would be set to comments data type.
Then every x seconds you set it to a random comment … or have a custom state as an index number and increment and set it back to 1 when it reaches the # of comments.
