How to Chat to Twitter Friends While on Facebook

Talking to Twitter friends with Facebook account, or chatting to VK friends by Facebook account is time-efficient, because we have to change social network services to [reach those friends] that means log out + log in+ find that person and then talk. It is time-consuming for me, also because I always be distracted when I change social network, such as refreshing the page to see what happened in the last minutes... These things really lower my efficiency. I found this tool helps me to do the chat thing straight to the point without my time to be stolen.
