Water spinach: Weed or soul food?

This weekend my wife cooked water spinach, a leafy vegetable eaten in Bengal, India, and South-East Asia. The leaves are also called Chinese water spinach or water ipomea; its botanical name is Ipomoea aquatica. My family loves the vegetable as a side dish, but I discovered during my research on the vegetable that it's considered a weed in the United States!
Sure, it is cheap, but I reject the classification. I love it stir-fried with garlic. I would say it is a soul food for Bengalis, who call it "kalmi saag" -- "saag" meaning a leafy vegetable, like collard greens.
Have you eaten water spinach? If yes, do you like it?

When you think of greens, what comes to mind? Spinach, kale, rocket leaves (arugula), lettuce, even mustard greens? How about bitter leaves? People in India eat leaves of the neem tree, a member of the mahogany family native to this country and Pakistan. The leaves are bitter, but take on a distinctive flavor when sauteed in oil or ghee. In Bengal, neem leaves are especially popular this time of year, when they are tender.
