One might consider granting a pass to these sorts of things because they appear on first glance to offer a way for "the little guy" to strike a blow against the corporate powers. But this is a dangerous illusion... because both practically and ethically, anything that the "little people" can do, the "big people" can do, too, only bigger and with a huge marketing push. In reality, all that is being created is the ability to slap arbitrary content into the middle of a web page, and if any of these services ever becomes large enough, it would be co-opted by the very same "corporate" voices is was created to provide a counterbalance to, in the end only making sure that not only do the corporations own their own spaces, but anybody else's they wish as well.
