Why even have those if you are, presumably, presenting yourself as the same person in each case?
You are person 'A' and you have the private key (and maybe password used to unlock the key) to prove this fact.
You don't need different private keys for each and the remote end just has a public key that says the account belongs to person 'A' and that key is public.

The only other real concern, site hacks/collaboration leaking where you're a member of by public key, wouldn't be alleviated by merely a handful of keys anyways: you'd need unique keypairs for each to be truly secure.
