Not sure if the personal interview model can be scaled as to include an appealing variety of startups. You may want to take a look at these two sites[0:2] that I think do a pretty good job at aggregating the stories of the startups that did not quiet take off.
Thanks for the resources! I will check them out. Also thanks for your feedback, we will think how to scale Failory to more startups. If you know of any failed startup please share them our contact.
You should use one emoji per question and use it as a bullet point. Right now, it looks a bit jarring. Your intuition is correct (a bit of color/playfulness doesn't hurt).
When you say as bullet point, do you mean as in before the text? That's not how to use emoji in general. But a single emoji at any place within the text (as opposed to many of them) is a good idea.
Yeah I mean as bullet point. For example, see my blog: dvt.name. I use emojis as "bullet points" on an unordered list of blog posts.
I'm not exactly sure what you mean by "how to use emojis in general" -- emojis are just like any other character used in any way that seems to make sense.
