Is there any competitor worth a look?
Edit: It's 20 % of all websites supposedly, not of all web traffic, but I think the point still stands

Anyway, I understand your concern with this huge monopoly. As far as I know, there really are no competitors. And while I can imagine being worried about the company's future trajectory, I like the way they do stuff now. They are very open about stuff, and they have an interesting blog.
That 20% figure makes some sense to me because a lot of small websites use it because it is affordable (the low, low price of free), and is so valuable to being able to actually get down to the content creation.
