I’ve had a few people using some of these online contact / address books such as Plaxo and now more recently Accucard/Accuscan. Now these services purport to keep all your contact details in a secure environment for everyone you wish to add. They also cross reference your details between you and other people that have stored your contact details in their files too. So the question is – with so many people using these now, how secure do you think they really are? Also have you thought about the fact that once you have stored your details or those of your contacts there, what these services could potentially do with them? Spammers? Just thinking….
