Each post in iMechanica is followed by a section called "Post your comments". This is a place where the readers of a post can raise a question, make an argument, or just share individual thoughts on the subject of this post. This is also a place where the author of a post can respond to the readers' comments by answering questions, or elaborating the original post. This way, mechanicians can interact with each other. More often, any thought-provoking comments may stir up a second round (or even more rounds) of discussion. This is exactly how popular web news forums, such as slashdot.org , form their dynamic community. For example, a hot topic there can easily receive hundreds comments in a short period of time, from which the subject can be many times elaborated than the original post.
