I think Gabby, if she wants it, will be in the spotlight and be able to largely support herself with those opportunities for some time to come. Like Shawn Johnson, Nastia and others who have become celebrity athletes. Though Gabby wasn't the 'star', gymnastically, of the final five, Gabby still has lots of fans world-wide, and well-deserved. I think her comeback despite knowing she wasn't realistically in the Repeat Gold AA race makes me love her more. That is a tough mindset- to know people less familiar with gymnastics may be disappointed that you didn't repeat Gold, to have just 'one job' (basically) to do bars for the team, let the newcomers have the spotlight you once had, and still step up and do your job and do it like a boss. So proud and happy for her.
She may be done with elite-level comps, but life in tours, appearances, endorsements, maybe announcing (if it fits her), shows like Dancing with the Stars perhaps...are likely still open to her. Even if she ultimately decides the celebrity scene spotlight isn't a fit for her more reserved personality, I hope she continues to be a part of the gymnastics-appearance scene and inspiring little girls and boys with all she has accomplished.
That said, I have avoided watching her family's 'reality show' so far - I do hope the editing of that show doesn't paint her or her family too poorly and ultimately hurt her in the name of quick ratings. 'Reality shows' scare me that way. I have a 'honey-boo-boo' knee jerk reaction to the genre... [shudder].
