TopCoder, Inc is 10 years this year!
I'm willing to bet this year's TCO come September 25 - 28, 2011 will be really awesome! They are ditching Las Vegas, Nevada as the traditional venue for TCO finals this year in favor of Fort Lauderdale, Florida.
Another significant milestone is the number of SRMs: TopCoder's 500th SRM will come up on Saturday March 19, 2011.
