This raises an interesting meta-question for founders and investors. How can you differentiate ideas that are "just not that good" from ideas that could be amazing, but need adequate investment and execution? I never would have guessed that team chat would take off the way that Slack has. (Part of the challenge of differentiating ideas is that even bad ideas can seem OK when you use artillery on them.) (What I will be wondering about is:) Now that we know that team chat actually was a fantastic business opportunity, and the primary missing piece was that no one had executed on it well enough yet, what signs could we have looked for but missed to tell us that? And can we look for those signs in new opportunities?
