It's quiet on the streets of San Francisco today, the first day of the RSA Security Conference, being held at the Moscone Convention Center south of Market Street. Traffic on the streets is light, so either the cops are doing a good job redirecting the crazy San Francisco traffic, which in this area can almost rival that of New York, or the gloomy economic news has trickled down to the streets. In Moscone Center North, however -- yes, there is a Moscone Center South and a Moscone Center West -- at the registration hall, things are pretty lively, all things considered.
