Mark Dimmitt, former curator at the Arizona Sonora Desert Museum, recommends people growing them indoors spray them wet with water every evening, if possible. He also says to soak them in a sink overnight once a week.
I'm going to guess most people who struggle with them don't water enough and don't give enough light. I've seen them sold as terrarium plants for arrow dart frogs, but I don't think most of those terrariums have enough light.
Oh... and most bromeliads are intolerant of copper. Don't use copper-containing fertilizer with these plants. Don't use water collected from bronze fixtures. Pineapples tolerate copper in fertilizer.

Thank you ES! Don't know if you recall answering a post I put forth about strange brownish marks on some of my tillies. You had suggested that perhaps they are sunburned? They still have quite a lot of marks on them, and the particular ones I speak of are really looking rough. I'm going to try the watering method you mentioned from Mark Dimmitt and see if there's any improvement. I'm thinking that what ever damage there is won't 'repair' it's self, but new growth will be clear of those marks.
