I'd be willing to do something like this. I'm too lazy to implement it (hence why we don't already have something like this) but I would enjoy something like the following workflow:
1. my firefox browser has an extension
2. if I think a website is interesting, I bookmark it to one of N bookmark lists (which can be arbitrarily categorized, whether topical like "tech rants" or Google+ style "IRL friends only")
3. the browser extension does some API calls to flush/fill each bookmark list to one or more of publicly accessible websites like my github bio, my HN profile, my blog listicles for one or more federated bookmarks, publishes an RSS entry, whatever
This approach does not require an account (except that I give the browser extension credentials/tokens to wherever it publishes), and it results in one-click blogroll sharing.
PS: the problem with this is the temptation for feature bloat.
Feature 2: on known websites with user profiles like HN, reddit, github, check the user profile for all users on the page and list out discovered shared blogrolls by username
Feature 3: reports such as 'most shared blogroll links' based on your own personal browsing history, calculated offline in your browser
Feature 4: ability to block blogroll links with a comment as to why you do so
Feature 5: ability to share your blocks with a given blogroll list
Feature 6: ability to follow shared blogroll link blocks from other blogroll lists, then editorialize that shared list yourself
Feature 7: ability to share your editorialized block list with others who trust you more than whoever you are editorializing
...and so on.
Though I'm pretty sure I'm reinventing lots of lost features from the web of trust and semantic web era.
A linked bookmark blog is essentially how many use Pinterest. Discoverability in part comes from shared lists because the related items on a given page are¹ based on what other things are included in lists containing the item currently being viewed.
Pinterest has a very strong visual bias, and often a selling-things bias with the stored links being to things you can buy, so there might be a niche for something like that with features geared around links more generally, or features specifically to help editorialising links to nows and other reading matter, though preferably without deliberately poisoning search results to over-favour the link storing site like Pinterest does.
