it does look at the URL in the person's twitter bio and will check that as a username, but only if the URL is the 'website' field. it doesn't check for a URL in the description field, but i'm open to adding that. what do you think

I see. I guess that would make sense for most people. I don't really use my website as a website currently, thus I'm not putting it into the website field. Some kind of heuristics for profile parsing would be nice of course :)
