We can surely be the top of that list. Once a lot of people see the benefit of Steemit it would really be awesome.
We should have something implemented like quora, ask any type of question and the best answer gets most of the upvotes. That could bring many more people to steemit as it will not only be a platform where you can share ideas and content but by asking simple / complex questions and answered by experienced users will bring a real unique sense to the Steemit platform.
I share your optimism regarding Steemit, but I think it will take a lot more time and it won't be a linear transition, most likely there will be a few bumps along the road. As for the difference between blogging and Q&A platform, I already said something in the post: there's a clear difference between them.
