It sounds like that can serve wikipedia, just without inline pictures. In fact, the cursory reading suggests that you can even have pictures if they're not in line. I admit that that's a small step down from the current experience, but it might be worth it.
Yes, that's true. Although in some ways that's not a problem with the technology; companies would hate it in no small part because it limits the anti-user things they can do, which is part of the appeal.
