I'm leaning toward this character's Trouble aspect being "The Buffy of YouTube - For Real", or some variant thereof. That is the most obviously interesting - and problematic - thing about her. "Blood on My Hands" probably belongs as one of her other aspects, rather than as her main Trouble, unless it actually ends up overshadowing the YouTube Buffiness of her. Then, see how much hay you and the other players can make out of that one Trouble aspect, story and back story, before dismissing her as boring. Other posters have brought up the issue of who might want her dead because of what millions can watch over the Internet. There is also the issue of what happens to those close to her, especially while the action is happening, starting with the cameraman.

For a more personal kind of interesting, think of why she keeps doing this, especially when it isn't necessarily safe for her or for her close confederates; come up with a motivation for her that grabs you. Does she like the fame, or the rush of excitement? Is she discovering a heroic streak within her? Don't bother to think her motivation through, because she probably hasn't. Just use ongoing play as a vehicle for saying, "How about now, when a wizard's blood is on your hands, and part of his soul is in you? How about now, when [insert dramatic escalation here]?" Then see what happens to her motivation. Is it affirmed, refined, rejected? Is it replaced by a more mature motive, maybe a more grim one? Play to see what happens, and have fun with it.

The stunt "Yeah, I'm Kickass" means that others will love, fear, hate or revere Kickass, each according to his predilections, that being how the Reputation trapping of Presence works. Since Kickass doesn't seem to be the kind of hero who can make a specific person revere or fear him at will, I wouldn't think that other stunts or boosts beyond "Yeah, I'm Kickass" would be necessary.

The text in YS190 about the Feeding Failure check could be written better, but is nonetheless not ambiguous. Taking stress from a feeding failure on the hunger track is one option; taking a mild (-2 stress), moderate (-4 stress), severe (-6 stress) or even extreme (-8 stress) consequence is another option; losing powers (-refresh cost in stress) is the third option. These options may be combined in any way desired; the last sentence in the second bullet point of that section is explicit about it. Losing powers is presented as the alternative to taking consequences; it is reading too much into the text to say that checking a box on the hunger track also means losing that much refresh of vampiric powers. Also, taking stress on a stress track and then having the same stress hurt in other ways is very much against the spirit of the game.

Too lenient? Feeding Dependency is only worth +1 refresh, at most canceling the cost of Blood Drinker or Emotional Vampire. It's not much of a rebate, and not worth losing powers just because you looked at them funny.
