Why didn't anyone tell me about this?

I discovered www.walkscore.com and it is amazing. It rates the "walkability" (i.e., convenience) of a neighborhood by assessing how many amenities (grocery stores, drugstores, restaurants, etc.) are within walking distance of a given address or intersection. Aside from the fact that my mom seems to be confused about its purpose and keeps calling it streetwalker.com (that would be something entirely different, though perhaps equally useful for some apartment-hunters), this site is way more informative than wandering around unknown parts of Brooklyn and hoping to find a laundromat.
