Why don't I see any akali junglers?

I was kinda bored one day and I got the idea of doing akali jungle, I played it on my pre-30 smurf account(With no runes) and I actually started to like it. I've played a few games of it on this account and she definitely has potential as a jungler. With no runes it was very difficult to farm early, but with quint of spell vamp it's not bad at all. Only problem is her ganks are basically useless pre-6, but it's the same with warwick.

Maybe it's because of the fact I'm only silver, but akali jungle seems to be working quite well for me. Why don't I see many akali junglers?

Have you tried jungling with akali?
