From Google's Inside Adwords blog:
What's new with Google Base since its initial launch?
Many of you may already use your Google Account to sign in and pay for
a number of Google services, like Google Video and Google Earth. Now
we're introducing similar functionality for Google Base: buyers will
have a convenient and secure way to purchase Google Base items by
credit card, and sellers can take advantage of easy to use transaction
processing as they manage their items. We're starting off
with a very small number of sellers, and we expect to include more over
the next several months. If you're interested in getting an
announcement when this feature is generally available ...
By providing buyers and sellers a convenient and secure way to purchase and sell Google Base items, we hope to make it even easier for people to use Google Base to post and distribute a wide range of content, from details about a family reunion to a used bike for sale.
I don't see a payment process directly affecting the aspect of job postings on Base, but this advancement does reflect an important progression in the evolution of the service.
