if( document.readyState == "complete" ) {
    conversationInterval = setInterval(viewConversations(), 30000);//30 second refresh rate
}

This sets a 30 second timer if, so it will open new conversations over time, say twitter updates while you're away, or whatever..

1 second is 1000, you can edit to any time, or use

if( document.readyState == "complete" ) {
    viewConversations();
}

but it might not work after scrolling down and having fresh information added.

You can press F12 to open developer tools, and go to console and type enter clearInterval(conversationInterval); and it will clear it.

Presently no form of session, so it will start on every page when you navigate around, and it will reset the timer if it has been cleared..
