Google has recently launched a new service, get your own free Google business cards based on your Google profile. This offer is so far only available if you have a continental US postal address (and upto 25000 cards) but I think this is a great idea and incentive for anybody who does not have a profile to create one right away. Be aware of also that until you have created one with a vanity url, the address you would like to have will most likely be taken if you wait, remember the early days of dot com address registrations.
