There is dear, you can have a private chat with anyone, simply go to steemit chat, look for 'search' interface and type in the username of the person you wanna chat with for example @maxdevalue, search for the person and it will appear, click on the person's name and send him/her a private message, if the person is online then, he/she can respond immediately otherwise steemit will send him/her an alert of your msg/chat. But first of all steemit chat demands another registration which doesn't take time to register, I advice you maintain your steemit username in your steemit chat registration for easier locating. https://steemit.chat/home
