I just set up my Yahoo! Personals personal; but it hasn't been without its conundrums. The whole point of the it is to make yourself as interesting as possible to the reader. Within poorly defined bounds.
Like any corporate venture, Y!P wants to make sure Y!P and as many other people are happy. So that means no contact information, and no porn. But what they don't tell you is that it means nothing out of the ordinary. You are supposed to post a picture of you sky-diving or hugging your dog.
You are not supposed to do crazy stuff like make a crossword puzzle and attempt to post it.
They rejected my crossword as being "Too generic". Of course, I never take an unreasonable no for an answer, so I wrote back.
