why omaha hi/lo over high

[brandysbich]

Is there any particular reason more people are playing hi/lo omaha than just omaha hi?

Pardon my ignorance if there's an obvious reason that i havent stumbled across yet, but so far i've only played omaha hi as its the only game out of the two that i could understand just by watching a couple hands....i have no clue whats happening in hi/lo (amdittedly i havent researched it too much as the thought of sharing a pot with someone after playing the whole hand hoping to win it doesnt appeal to me)

Anyway just wondering what the fuss with hi/lo is? thanks
