On game giveaways from this weekend (4/24 & 4/25/2010), the link at the end of the comments page, with text "View all comments >>" takes you back to the beginning of the page, not to the rest of the comments, so only the first 3 comments are accessible.
Also, the last time I tried, the thumbs up/down links were not working, either. This was when the giveaways were still active (I don't know if they're supposed to work after the giveaway is over).
I also submitted these problems via the Contact Form for the site.
