I removed the section "richest/best educated zip code".  I didn't understand what it meant how can Waban be the richest/best educated zip code without being the richest?  Also, how do we define "best educated"?  I looked at the census data for 02468, and there are lots of statistics that might mean "best educated" largest fraction with bachelor's degrees, smallest fraction of high school dropouts, etc.   
 I'd be glad to see this section come back if someone could sharpen it to some verifiable fact, and provide a reference.  It would be very interesting if it were true that, for instance, Waban has a higher fraction of people with graduate degrees than any other zip code.
