I'm currently reading "In the Plex", and I couldn't help but amazed by Google.
(Well, I am always a fan. It's not a secret. I always love to tell the younger generations how painful it was to search for information online during the "pre-Google-era". The "physically finding information in library" way of research is almost unspeakable.)
When I read about the stories behind AdSense, I decided to add an AdSense to my blog too. Not for making money, since I never plan to draw any audience to this half-diary, but more for better understanding. I'm not those genius geeks so I don't really plan to understand the algorithm behind. However, I'd love to test it out, to randomly check what are the advertisements showed. I haven't really completed the appropriate setting so Google crawler now unable to access my page to determine its contest and display relevant ads. I shall monitor for at least a month before I allow the crawler to access.
So excited to see the results :)
