Very cool idea - starting a conversation on an image.<p>The issues I see:<p>1) The image(s) are easily obscured by comments.<p>2) Alerts, alerts everywhere.<p>I could see this having a very broad appeal to any type of community that uses images. Making an image and submitting it to reddit may be a great way to get traction (the image would be the marketting, the conversation would be extra).<p>I liked being able to comment anonymously and was disappointed when I couldn't continue to do so on the creepy house pic - I could see this really taking off.<p>Good Luck!
