It stands for Your Success Network, and is billing itself as "a networking site where you can do more than stalk your Ex". Because that's what people use MySpace for, presumably. Forget all that music rubbish.
Sorry, not to be cynical. YSN is the work of motivational gurus Jennifer Kushell and Scott M. Kaufman, who you may know from their book 'Secrets of the Young & Successful: How To Get Everything You Want Without Waiting A Lifetime'.
The community claims to tackle the big questions facing college students, such as whether it's wrong to eat last night's kebab what they're going to do with their lives, and how they're going to do it.
Besides regular social networking features, the site has self-assessment exercises, customised action plans, themed groups ('True Life: I'm An Executive Assistant'), industry Q&As, and discussion forums.
"We spoke to thousands of young people - from Harvard to the inner city - and found they ask the same questions," says Kushell. "What will make me happy? What's out there? How can I pursue my dream? YSN.com helps uncover real answers and build a solid foundation for new lives and careers."
I can scoff all I want at the motivational blurb. Someone - probably Paul McKenna or Ruth Badger off The Apprentice - will launch a UK community in this vein during 2007 for sure.
