LSB cannot help you if you want to hide text (or any data) in text, it can be applicable to images, or, at least, to something with relatively big "words" each carrying relatively small piece of information, like in case of pixels. If you try to do anything like that with text, it will be dramatically mangled. I hope it looks obvious.

Some approaches are explained here: http://en.wikipedia.org/wiki/Steganography#Digital_Text[^].

is there any other way to hide text in text rather than LSB

Not quite a correct question. There is no LSB method for texts, so you would need to ask "is there any method at all?". All methods I'm aware of are listed in the "Digital text" section of the Steganography article I just referenced. Consider them or invent something else.

For example, my own, very simple idea: hide a little of information in a really long text with scattered spelling mistakes in it. These days, such mistakes are very usual on the Web, so they may attract little attention. Each mistake may carry a byte (or even a bit) of data, on some criteria. The processing software should use a dictionary to check up spelling and be able to locate "close" spelling. Spelling mistake location, or some number inferred from "correct" and "misspelled" letter may be considered as some code point. Simple, nearly stupid idea, but it will work.
