What about a startup is the most interesting?

Hey guys, I'm working on a startup for startups (intentionally vague at this point) and need your opinion

What are the most interesting bits of information about a startup?

KillerStartups asks 1) "Site.com in their own words" and 2) "Why site.com might be a killer".

Personally, I enjoy reading about the background of the founder(s). I'm also interested in knowing whether it is bootstrapped or funded.

What about you? It would really help me out if you could answer this question for me. Thanks!
