Not totally or inherently useless, but not very practical. You would
still need encryption as well as information hiding, so the only use for
it is to try and hide the fact that you are hiding something. That is
very hard to do. You may thank your friendly neighborhood statistician
for that.
I am aware that encryption is still required; steganography will
commonly be used in concert with encryption. As to the feasibility of
detecting steganography,
Not really apropos of anything, but the encryption remark is just a
reminder. I would expect anyone to know that who spent much time
thinking about the subject.
Feasibility-wise, it's really anybody's guess whether information can
remain hidden. I see no reason to use steganographic techniques, except
to hide something from an authority.[*] In theory, it should be
possible to detect hidden content in anything, due to the added
complexity of the hidden content. In practice, it has been becoming
easier to do so. Reading the information is a different matter.
However, once it has been realized you are hiding something, the point
is moot. You will be hounded until you give up the hidden information.
The authority in question will not give up, ever.

(*) Perhaps I am ignorant of the subject. But I can only think of
hiding info from, (1.) A government or police investigation. (2.) An
employer (3.) A(n) (ex-)significant other, or stalker (4.) You are a
purveyor of malware, hiding your product from the user. (5.) You are a
student, hiding mp3s from the RIAA. If there exist other reasons for
the deception, I am sure you will enlighten me.
