What you say is right, and occurred to me, too. But there's another sense of "alternative" at play--not that the list is an alternative to another list, but that these sites are alternatives to more commonly-noted ones. There are a handful of modern wonders lists, and they (and other media) often focus on a few "usual suspects", like the Taj Mahal and Machu Picchu. So maybe in the spirit of the post it's "Some wonderful sites you may not have heard about", and that doesn't seem like a bad thing.
