I've had positive experiences with having my questions answered using chat widgets from Codeship, AppSignal, Intercom themselves (they are a chat widget provider), Datadog, Packet.net, and more. Maybe it's specific to the SaaS space, but I tend to reach for the live chat right off the bat if I have a question. If nobody is online, usually they still get back to me by e-mail anyway, which is no worse than if I had just sent an e-mail.
