I've had keys on the keyservers for years. Any spam related to
harvesting key data is negligible compared to spam from other sources.
Regardless of source, it gets filtered out so it's no worries to me.

While I don't use OpenPGP at my work, it seems reasonable to me to
create separate primary keys for work and personal use.

In the US at least, companies have various regulatory requirements
relating to communications and message storage. It may be compulsory for
a company to have the ability to decrypt, read, and archive your
work-related mail. Since you cannot -- as far as I know -- bind
encryption subkeys to a specific UID, having a separate primary key for
your work seems like a good idea.
