On most websites nowadays, you'll see somewhere on the page, usually at the top right corner, links to the site's RSS feed, Twitter account, and Facebook fanpage. I've always wondered why MySpace, being the second largest social networking site by far, isn't on that list.
Yeah, I used Friendster back in the day. Although I have to say after the initial sign-up, friend connections, and testimonials, I stopped using it. They billed themselves as a dating site - a safer and more casual way to get introduced because you're meeting your friend's friends instead of a complete stranger like it is with Match.com. I wasn't looking for a date back then, and I felt too embarrassed to ask friends for introductions, so I had no reason to go back to the site.
