Hey all, Joe here from the marketing team at Intercom. Unrelated: we're a Moz customer and I'm a huge Rand fan and Seattle native. 
Until today, it wasn't possible to use Intercom truly as a live chat tool for anonymous, logged out visitors to your website or app. You would need to have an existing account or login already to enable the chat-like functionality.
But thankfully, no more. Voila:Â https://www.intercom.io/live-chat
Intercom's vision is to build a central platform for all your customer communication. Having a CRM, email marketing tool, marketing automation system, live chat tool, helpdesk, etc. as separate entities provides lots of difficulties, notably in integration of them technically and functionally. We're hoping to change that.
If anyone has questions about Intercom, I'd be happy to help or put you in touch with someone who knows more than me. I'm joe at intercom dot io.
