Odd, I've never seen those. While some of my friends (bless their hearts) are not quite au fait with the how-to-avoid-spamming-your-friends thing, I don't think any of 'em have ever added any apps quite that annoying.

Then again, I wasn't born in July, don't have a name starting with S, and am most definitely not a Saggitarius Chica, so maybe I'm just missing out.
