The differences are rather stark.
The ones you're not paying turn up because they have some specific thing to say that they think will be interesting (e.g., about the relationship between religion and rationality). They behave more or less like typical Less Wrong participants.
The ones you're paying turn up to gush in the comments to your articles about how wonderful the articles are, and how great Intentional Insights is, and how excited they are to be growing in rationality (without any specifics about what they've actually learned and how it's helping them). They behave more or less like typical blog comment spammers.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
