It's a cool implementation, but I see one major flaw: unlike HN and other social news/submission sites, its popularity ranking doesn't seem to factor in when items were submitted.<p>Hence, if you take a look, the top three items there were submitted 3 months, 4 months, and one year ago, respectively. That might work for Best Buy's intentions, but generally that wouldn't make for a very sticky/relevant site. Would really like to see them incorporate date of submission into rankings.
