Amazingly detailed and easy-to-access demographics on Google Maps

It's insane.  They have race and ethnicity, income, housing prices, education, presence of gay couples... all down to the block level.

This is incredible stuff.  Learn more about your neighborhood.  I've learned a lot more about San Francisco.  

Alternatives to Del.icio.us?

It looks like Yahoo might shut down Delicious, which frustrates me as it is one of the more useful services they offer.  Does anyone have good suggestions for alternatives, especially alternatives that have an easy-to-use import tool?  

Now, if they decide to shut down Flickr, I'll *really* be upset.  They're my image hosting service for just about all the photos in this blog.  

Thanks!
