Note, that while Calcanis thinks this is a commodity business, well, you might not think blogging would be what is has been when you first heard about it… From an enterprise perspective, I can say that this is definitely exciting, and from on the larger-scope (think Memex, Xanadu [or as Jot likes to put it, Excel]), it’s even more promising. Of course, I could be biased.
