Is minority here referring to being outliers in the age distribution or "a sociological group that does not make up a politically dominant voting majority of the total population of a given society"[1]?
If it's the former then you should say "in the minority" or something. If it's the latter, and you're not making this an issue of racial discrimination then you need to change the headline to something like "Two 11-year-old entrepreneurs learned the hard way what it’s like to be rejected during Startup Weekend".
You said that wasn't the point you were making: ie. that the point you were making was not that "being a minority" (read: ethnic minority - being young does not constitute being a minority since everyone is young at some point in their lives but not everyone is black, for example) influence the outcome for these two.
Now you're saying that you were making that point - but that you're saying that they were both a minority, and "minors" in that they were so young.
I think you were quite clearly link baiting here using the race card even if you're not admitting it - however the story clearly shows that these two couldn't get serious hackers to work on their ideas because they're 11 years old. I seriously doubt that their ethnic or gender minority status had anything to do with their outcomes at this event.
Also you've described Marci as a woman. She's 11. She's not a woman, she's a girl. You couldn't even describe her as a young woman - she's most definitely a girl.
Comparing age based prejudice to race or gender based prejudice is erroneous anyway. Discrimination based on age (in the case of exclusion of young people from certain activities) is entirely appropriate. Discrimination and exclusion based no race is never appropriate and gender based exclusion is rarely appropriate (I say rarely since exclusion of women from competing against men in, say, professional rugby is a safety issue).
We were all young once, but I've never been black and I've never been female (although I could approximate the latter through surgery if I was keen).

Being on blackweb20.com, I would assume "minority" is referring to race here. Wayne, you may want to update the title here if you want to avoid some confusion.
(Wayne: By the way, I'm in RTP and just noticed your trioutnc site from your profile - looks like a nice tool so far, i'll be trying it).
