Geocoding services comparison

We analyze the feasibility of boostrapping a location service through geocoded postal addresses rather than the common wardriving technique. A location service that contains the MAC addresses and geographic position of wireless LAN access points enables positioning services for WLAN devices and location-aware networking protocols. This work thus compares the accuracy of access point position estimates obtained based on RF signal strengths readings (wardriving) with the accuracy of the geocoded postal address. The results show similar accuracy for geocoding in comparison to typical wardriving studies, with significantly reduced effort if postal addresses of access point positions are known.

The US Census has a free database called TigerLine. It's not always accurate. I've worked with it and field surveyed some glaring anomalies.
Now, I'm not sure MapQuest and MSN Maps are derived from TigerLine, but chances are they are. I recall researching some commercial geocoding services that purportedly enhance the accuracy of TigerLine.
If you email me your address, I could check the TigerLine for the bay area and see if the anomaly you noticed correlates.
