What are top 3 things Musing need to get right for it to go Viral /successful ?
1) Rewards: Access to capital for growth
The key differentiator of Musing over Quora is the distribution of rewards to users. In order to maintain the rewards as the platform and user numbers grow, Musing will need a source of available capital. This could be obtained through external investors (or existing Steem investors), advertisements, SMTs sales, or by offering SMTs directly as rewards.
2) Q&A bank: Quality product
The Q&A bank that results from the Musing process is a valuable resource that will attract general internet users looking for answers through search engines, thus increasing user numbers and hits. The value of this Q&A bank will be highest if answers are of good quality and if questions are specific, i.e niche rather than general. I think Musing has this right in the main already through their incentives, with the exception of aggregating / consolidating similar questions to prevent duplication which could lead to fragmentation of searches.
3) User numbers: Controlled growth
Higher user numbers will be the other key factor to success. This will need a simple sign-up process and ideally a simple reward process (to the extent that this can be changed in future, for example removing curation). However unlike most internet businesses which have almost limitless expansion, Musing may have to temper growth by the amount of available capital to manage the available rewards and the quality of the experience. Some form of periodic open/close for sign-up may be appropriate. This could also serve as a marketing tool, re exclusivity.
