On a lark i threw it at Reddit and found that it got the layout mostly right. But as it lacks JS support (no surprise there, JS is quite the beast) i could not do much beyond look at pretty pictures.
Edit:
Heh, threw it at HN and it worked fine for the most part. Trying to search just resulted in a blank page though. And throwing it at some news pages didn't exactly go "well" (and i reminded myself why i have no love for The Verge). Funny thing is that without all the JS and CSS to parse, even the biggest news sites came up in a matter of seconds.
