Interfaces for personal CRM

I was searching for a personal CRM to maintain my relationships. There are tools on the market, but I thought as Capacities is object related, this can be handled in Capacities as well. As many functionalities can be used to build a personal CRM, an interesting addition to the exisitng feature would be interfaces to the main social networks to be able to retrieve information from e.g. LinkedIn, Google Contacts, Intra, Facebook ... into a person object to keep the persons information up to date.
