This morning I setup My Yahoo on my iMac. The good news was the ability to import all my iGoogle settings into My Yahoo. You first need to go to iGoogle, Options, Settings, and scroll down to the bottom of the page where you'll find Export. This will create a xtml file which can be imported into My Yahoo.
There are a number of alternatives. I chose Yahoo hoping they would be around for a while.
Now I need to work on customizing My Yahoo page.
What are you using for a Home page?
