How I was Advised to 'Get Laid' when Voicing Negative Feedback

Some days, the Internet is full of wonder. Other days, some random person across the Atlantic advises you to get laid. This is one such story.

It all started innocently enough. A content service company - Writing Bold - had sent me three emails offering their services. You know the kind:

This is Wavedeck: http://www.youtube.com/watch?v=qqYycJnCxE0

It's a fast video messenger, and it marries the ease of audio with the humanity of video. You kind of need to use it to get it, here's a [download link](https://itunes.apple.com/us/app/wavedeck-fast-video-walkie/id489188581?mt=8).

Wavedeck has been through a lot in the last two years. Several major iterations, a pivot, two [well](http://jacobian.org/) [known](http://sealedabstract.com/rants/why-mobile-web-apps-are-slow/) developers. We shifted our plans and resources until we found the right product, and now we're there. Wavedeck is growing and it needs you to grow up with.

Your job is scaling and building Wavedeck's future, we have some really exciting features planned. Our existing codebase needs to be put on some solid ground, so you should enjoy bringing order into a complex system.

The job has some hard requirements:
