Nivin Sewpershad has written a detailed account of how he managed to get his whole family on Twitter.
By having us all connected, a member of the family could ask a question or say what they were doing. If one of us was not at our computer we would receive it on our cell phone, and could reply from there or jump on a computer. After many “Hello you twit” messages from my father, everyone seemed to understand the basic workings.
It took a bit of work convincing everyone initially but once they were all on Twitter they loved it. Good work Nivin!
