It's not surprising NewMe didn't get coverage. Taking part in a race-selected accelerator, instead of a quality-selected accelerator, reflects badly. "If their product is so good, why couldn't they get into YC or TechStars?".
Hmm...two curious assumptions here: 1) that a "race-selected" accelerator is not a "quality-selected" one and 2) that the NewME companies are all YC and TechStars rejects Curious what led you to them.
Step 1) Throw out 87% of applications randomly. Step 2) Select based on quality. Step 3) Profit?
Compare that to a quality-selected accelerator:
Step 1) Select based on quality. Step 2) Profit!
A race-based accelerator will only outperform a quality-selected accelerator if there's a race that inherently, innately outperforms all other races. Science has pretty well debunked that one.
As to #2, you'd have to be really, really, really stupid to go with a niche accelerator that no one's ever heard of IF given the option of going with YC or TS.
NewMe could barely get a mention in TechCrunch, and, when they did, the social entrepreneurship side story beat out the "here are our awesome companies!" story.
