Suggest to HN: user profiles / links to homepages

A few times recently I've found a HN commenter who seems particularly intelligent or insightful, and have clicked on their profile name, hoping to get a link to their home page. (Yes, yes, a smarter person would only do this once - I forgot each time that I'd done it before). It would be nice if we could add a URL, a twitter handle, and/or one paragraph of text to our user profiles. That seems to be the norm these days at most sites.
