Only a handful of people on the Internet are sane.

Advantages of .mkv:
New features can be added easily instead of having to hack them in like .avi
Softsubs
As a result of the above, fully customizable subs (so I don't have to look at some shitty ass subber's idea of a good font)
Native support for stuff like 5.1 audio, multiple audio tracks, etc.
Better audio compression.

Disadvantages:
No faggy ass blinking karaoke openings.

That about wraps it up.
