i'm kinda new to the list myself, but since i've been so vocal about this
type of thing i'll take a shot at answering you...

if you add multiple IDs to a key pair, then each ID "points" to each other
ID. this shouldn't be a problem as long as you don't mind that anyone who
knows you from work also know you from your other business.

on the other hand, if your employer doesn't want you to have you
conducting other business on the side (or the type of side-business is not
acceptable to the primary employer), then those two IDs should each have
their own key pair. of course there are other methods of discovering that
two email addresses belong to the same person, but those are (mostly)
beyond the scope of pgp/gpg.

basically, adding IDs to a key is a convenience, while creating new keys
for each ID helps to keep those IDs unrelated to each other.

this is one of the practical aspects of pgp/gpg where the right choice
depends more on social issues than technical issues.
