Rowan, as you mentioned in the call today, ideally we'd want tools like this to be adopted virally, however from a marketing perspective I did a little test vs. the other competitor you mentioned "Slack". When I searched google for Spark, every search result on the first page was related to slack.com and its app. When I searched for "Spark", not a single entry was for Cisco's Spark. I know this by itself is insignificant, but let's allow the general public to discover Spark in an easy manner.
