'StreamWriter' inherits from 'TextWriter' and extends it. Note that you
cannot instantiate 'TextWriter' because it is marked as 'MustInherit'.

IMHO, another point about being extended of StreamWriter/Reader,
that's compatible with "Using" statement which performs automatic
dispose / close methods. If you use TextWriter/Reader you must
explicitly use close / dispose method.

How would you use 'TextReader' if it cannot even be instantiated?

Just wanted to point out "Using" statement is used with StreamWriter
not with TextWriter, but i can be wrong, sorry.
