See how Jack Mallers is already linked from the Jack page, but Jack Dorsey is just a string. When a link is created from the Jack page to the Jack Dorsey page the string becomes hyperlinked and both posters are attributed for the creation of it,  nifty eh?

The tx which created each listing is linked as is the timestamp and the link to the posters account, so reputation matters and can be cultivated over time even though the accounts are anon.
