I remember the original "theme-based" approach, but it was a bit idealistic and not as embracing of change as iterations. Maybe that's why iterations were adopted by much of the Scrum community? Do you think Scrum adapted to take bits of XP that were more adaptable than Scrum's native approach, or do you think it was a misunderstanding/bastardisation? I'd be interested to hear your thoughts on that.

And may explain the growing interest in Kanban?

The only reason would be to buy a topic-based domain. For example, I'd have taken wine.blog and expect food bloggers would like food.blog and so on. But, I won't be buying bigpinots.blog as I already own the .com
