I used to read, and once or twice contributed to, alt.cuddle. At that time (1995) it was not nearly as nauseating as slappyjack says, but it was extremely high-traffic, which is why I stopped reading it. It was then a good place to go when you were feeling down, because people would be nice to you (something hard to find on Usenet). I wouldn't be surprised if it had morphed into something less calming and more sickeningly sweet as more people found it, though.
