"Provisional Patent Application" costing more than $110 to file, the idea for hashstamp-world may have been inspired by the old-style inability to edit/delete slashdot journal-entries/comments. The lone inventor's nightmare, the big company claim "Anyone could have thought of that, in fact, we were Just Getting Around To That.". In hashstamp-world, you would routinely "file" the hashes of your efforts, making "Prior Art Claims" nearly free.
So for the NEXT iteration of slashdot, for a fee, you could allow locking a Journal Entry against modify/delete.
Journaling the hash of your self-portrait and thus locking it would allow resolving password-stolen-claims, while maintaining anonymity in the meantime.
