I've been using these for a while as well, but watch out for: 1. Roads whose names were changed by local ordinance after platting, frequently to honor some politician. 2. Roads that are platted, but never built because the money runs out. 3. Roads that are built, but later abandoned. We have a lot of these along the Fox River NW of Chicago where old subdivisions were built in floodplains and were later bought up and bulldozed by one gov't agency or another. 2 and 3 are easily solved by cross-referencing with satellite imagery, but 1 can be tricky. This is where TIGER 2011 can come in handy. Kane County, IL actually has subdivision plats all the way back to the 1850s online, which can be pretty cool to look at in their own right. -- Kristian M Zoerhoff
