In the spirit of a free-form Friday on StackOverflow, I'd like to know if I should consider learning ConTeXt. What got me into LaTeX way back in 1994 was having structural markup that made longer documents easier to write. What got me into XeTeX was being able to use my Mac's fonts just like I could in a word processor. What makes ConTeXt users passionate about it or at least willing to forsake LaTeX?
Edit: Thanks for all the answers and great discussion in the comments. The whole page deserves a green check. Success! I am now interested in ConTeXt.
