It will just be different. No profit train lasts forever. Google is about to be made utterly irrelevant after 20+ years or so as a company. And they were the best.

If you still have a connection to your readers (e.g. email) you can still reach them. If they've formed a community, even better. If not, its a good time to work on that.

Google doesn't really have that. I have zero sense of community with Google. And that's why they'll die if something doesn't change.
