I'd love to, but after I click the link, I get another link to "try" it. Clicking this link still gives me no joy, as now I need to find a server or something? Ok, lets see if there is one for my country, USA. Nothing on the popular list. Guess I should try the complete list. Oh look, no way to search. No suggestions on what I should be doing.
Whatever, I could spend my time and energy figuring the rest of it out, but there is no way I am going to convince my girlfriend this is a good idea.
This is why Slack is taking the world by storm - the chat window isn't all that good (in my opinion), but the onboarding process is buttery-smooth and completely frictionless.
