Whenever I have tech discussions with friends I would recall something mentioned in a article I read via HN. But it would take me a whole lot of effort to get that link. Oftentimes I simply couldn't get hold of the link even after an hour of searching.
Please do get the Firefox extension out. Would love to use it. Also, please do make sure the extensions/addons are stable. Have been facing problems with Annotary's extensions [1], for instance.
By the way, do you have a crawler fetch the link content or do you send it from the user's browser?
