What is iGoogle?

I just had someone thank me for explaining what iGoogle is because (they said), they couldn’t figure out what it was from Google. Apparently, when you search Google for What is iGoogle?, the first page results links to a rexblog post with that phrase. So, I thought I’d provide Google with a little Google juice by pointing to the official Google answer for the question What is iGoogle?

The unofficial answer is, “Something that has nothing to do with Apple.”
