This is a tool which should be very usefull if you make use of Lotus Notes and if you have a lot of contacts on social networks and if you always wanted to sync both worlds …
“Keeping track of all your ‘virtual’ contacts on the various networks will is not easy, especially as the quantity of social networks you are registered to increased, and your global network increases as well. Locating a user you wish to collaborate with, can become tedious and subtract from the effectiveness of the networks and the effectiveness for you to be able to locate a specific user.
ViCo for Lotus Notes can help with this by importing all of your contacts from all supported social networks and providing them in a single point of access, a Lotus Notes database, allowing sorting and searching and categorising of the documents by network. The product also allows you to add specific contacts onto your Personal Address Book in Lotus Notes, making those contacts available in type-ahead searches from within the Lotus Notes mail file. The application also allows automatic synchronisation of changes of contact information direct to the Personal Address Book”
Unfortunately this product is not for free (approx. 49 euro/license). See this the Notes-Solutions website. Maybe a free version should be made for personal use as a lot of companies still do not see the benefit of social networks
