Ah ok, they talk about that on the page I linked too:
"Yahoo! GeoCities Plus customers: Although GeoCities has closed, your friends and family
can still view your web site as usual. However, you can no longer access your files or update your pages with GeoCities tools. To update your site, you'll need to upgrade to Yahoo! Web Hosting. You can now upgrade at no extra charge for five years. See details or upgrade now.
When you upgrade, we'll redirect your GeoCities web address to your new domain
There's actually some good info on some of those pages like the indy 500 winning cars search. But it's not fresh tho, since it was last updated in 2008.
We'll see how this turns out. With my sites/wordpress, I usually don't do more than 1 post a day, I spread them out. I love the feature where you can pick the date the post goes live. So if I took a month vacation
or something, I still have pages going live while I'm gone. One site I have a page going up every 5 days, other sites spaced differently. So all my sites always look "active"
