The one startup I've been really expecting to see launch today at YC demo day was Diaspora, but I didn't see them. I know they got into YC (Remember seeing them on an article about that), what's going on?
They made a fatal mistake in building a Rails app. That led them down the wrong path for an ecosystem that needs to be a decentralized protocol. See tent.io, they've got the right idea. Not sure if they'll be successful, but work in this area needs to be at the protocol level, not at the application level. And as soon as I heard what they were doing I knew they were toast.
Diaspora, the software, works reasonably well, although it obviously suffers from a shortage of users. You can sign up at eg. http://diasp.org. Dunno what's going on with Diaspora, the company.
But agreed, it seems like they're abandoning their core product. Not that it's gotten much traction in the last two years, but if they were going to abandon it, I wish they'd just say as much.
How is Makr.io even a real product concept? It appears to be a very limited version of the G+ image editor.. or any other meme maker in existence but with "SHARING" (remixing)
It's a hobby project, that's all it is. Not a real business to be taken seriously. Give them a few years, and they will be looking for a corporate day job. Nobody can live off venture capital for the rest of their lives.
