While I originally joined the likes of Facebook and Bebo just to look at the application and general layout of each one I have found it a great way to connect with distant and not so distant relatives & friends.

Been There Gone That
There are the social networks I used infrequently and now they are gone, like ….
Bebo I didn’t use some much and its gone now ! I never got a chance to export the few things I did have up there.
Plaxo was another business type social network I didn’t really use that much and in 2017 I had to completely export the contacts I had in there as the site was closing down.
