I'm the co-founder and CEO of PeSoMe.com which is a brand-new Multi-platforms creation concept. PeSoMe lets users create their own platform and those could be either a Social Network, a Website, a Blog or an online Classroom in 30 seconds from start to finish and it's completely for FREE.
We received rejection email from YC last night and we think we knew the reason for it. We will put together a better presentation for the coming batch.
