Recently I received a series of invitations to join UNYK, an interesting relationship site. Its focus is an automatically updated contact list: when your contacts update their details, your contact list is automatically updated, and vice-versa. Given the nature of the information, I was worried about privacy/confidentiality and data openness, so I did a little web search.
Since I bought my cellphone (a Nokia 2630), I back up my data systematically. Someday I’ll start synchronizing it to Evolution, but for now it’s good enough. I would adopt UNYK only if it made it easier, not harder, to keep other contact lists.
