Today someone asked me what my role is at @GDI_FDN After I explained what we do he told that I look/sound like Gilfoyle (@MartinStarr) of Silicon Valley. So I found a clip and edited it so it would fit my narrative. But you should watch all the episodes on #SiliconValleyHBO :-)

Yep now it's happening, @23andMe just filed for bankruptcy and the DNA of 15 million people will be sold to the highest bidder. There's not many actions users can take now, but I'll add some supposed steps you could take to attempt to protect your privacy below:
