Longevity - most definitely. Not a lot of people get to, let's say 3+ years. I've only been able to do it once, either because I got bored down the road or started to lose (or even win!) a lot. So you gotta find the way to stay engaged.

Presentation - Personally, I've always put this first. I don't want to just write. I've always wanted to add photos (videos if I can), to take it to another level. You gotta have free time available, obviously.

Creativity - Storytelling it is, here. People make sorts of "the career of" and write a story, I think you gotta give extra points to that. It has to be unique too, either by longevity and/or presentation.
