The Yahoo Niles group is timely but disorganized. It is hard to find anything not from the past few days. All groups on Yahoo are forced to fit into the same general structure. This HotDoodle(tm) site instead lets members establish its structure and content.
There are also some simple but profound advantages of HotDoodle. Examples are being able to edit or delete a post after it is made. This way corrections do not need an entire new post and when a "for sale" item is sold, it can be removed from the list with just a click of the edit icon next to it.
