Sometimes I write stuff here not because I know things, but rather, because I would like to know more, and I think the audience of this blog may help me find the material I need to become more knowledgeable on some topic. Having a blog is a privilege, in the sense that the one-to-many communication it establishes between the writer and the readers allows the owner to sometimes have access to the (all together vast) knowledge of his or her readers.

I cherish this one-to-many communcation means and I am grateful to you for it.
