Is it Christmas yet?
How could I possibly gush over this web site without over-stating its design, its functionality and its utility? I mean, think about it—the site is pure, functional and maintains a staggering track record for being extremely accurate. It answers a fundamentally important question to millions of people on this planet: Is it Christmas?
It even has its own RSS feed for your reader. Every day as you read the events pouring through your RSS aggregator you'll be alerted that today, for example, is not yet Christmas!
