Some ways I would describe this site are “tracking belief changes over time”, “recording beliefs with high fidelity”, “creating a repository of beliefs”, “querying your mind from multiple directions to elicit accurate beliefs”, and “the longest interview ever”.
The boring way to use this site would be to just read other people’s beliefs using the belief portal or the user portal. The more exciting way to use this site is to go ahead and log in and add some beliefs.
