I actually find it disturbing that there are more dogs than kids. Not that I think everyone should have kids (in fact, I think quite the opposite), but as someone who is not an animal lover (I hate to say that here), it is hard for me to understand how having a dog is the same as a human child. Intellectually, I understand how a pet meets our needs, it's just personally, I don't equate the two as the same.
No flames, please. Of course, people with common interests will want a place to meet together. Just like cyclists at coffee shops! The rest of the article is interesting, but I think they went on a bit too much about walk in closets!
