The best - and, well, the worst - of Internet culture will crawl out of computer screens across the globe and descend on the Massachusetts Institute of Technology Friday and Saturday for the first-ever ROFLCon, a joint venture of the Harvard and MIT Free Culture programs that will feature more than 60 Internet celebrities, guest speakers and college professors.

"We're getting the Internet to appear in the real world," said ROFLCon organizer and Harvard senior Tim Hwang.

If you don't know that ROFL stands for "Rolling on the Floor Laughing," then chances are you've never marveled at the luminescent costume detail of Tron Guy, giggled to grammatically depraved kitty captions on the Web site "I Can Has Cheezeburger" or hopped aboard the meteoric rise of the "Stuff White People Like" blog. That site garnered 24 million hits over a few months and landed creator Christian Lander a book deal with Random House Publishing.

Last month on Craigslist.com, someone who described herself as a "spectacularly beautiful" 25-year-old placed a personal ad seeking a husband who made at least $500,000 a year, because "$250,000 won't get me to Central Park West."

As her post hit the blogs, it received a scathing response from a man who said he fit her description and told her that her proposition was a bad business deal. "In economic terms, you are a depreciating asset and I am an earning asset," he wrote, because "your looks will fade and my money will likely continue into perpetuity."

Last week, this exchange spilled over into the e-mail world, where the it turned into a popular item to send to friends as a joke. The difference between this and other outrageous share-mail messages, however, was that instead of remaining anonymous, its ostensible author signed his name and the company where he worked, which happened to be the investment banking division of JPMorgan Chase.
