When I realized how much my online activity cost me in terms of time and money, I decided to sign up with Google's AdSense program. I'm still waiting for the confirmation mail from them though.
One of the projects that I currently handle is that of creating a site for primary sources for Philippine history. Three days after I created philhist.pbwiki.com, it's already the top 1 site for "primary sources, Philippine history" at Google. But there's nothing there yet, and instead I have started building content at philippinehistory.googlepages.com.
My primary reason for switching to GooglePages is the ability to host AdSense ads in the website. But the GooglePageCreator is not as user-friendly as PBWiki's editor (or maybe I'm just more used to PBWiki's editor).
What I really love about PBWiki is the easy editing. Unfortunately, it only offers 10MB to free accounts. It's true that AdSense ads are allowed (one of my primary reasons for transferring to Blogger.com from Wordpress.com), but 10MB will sooner be depleted.
I have decided to continue my work at GooglePages, then just put a big link from the PBWiki site.
