After reading countless negative comments, many written based on real experience, but almost all tinged with fear, and even a few ad hominem attacks ("...not really experienced" and "...just more lispers?" Really?), I'd like to offer a word of encouragement.

I'm thrilled to see someone try something different, and grateful that he wrote about his positive experiences with it. Perhaps it will turn out to have been the wrong decision, but his writing about it is the only way we'll ever really know. It's so easy to be lulled into a sense of security by doing things the conventional way, and to miss opportunities offered by huge improvements in hardware, well-written open-source libraries, and powerful programming languages.

I have an especially hard time with the idea that SQL is where we all should end up. I've worked at Oracle, and I worked on Google AdWords when it was built on MySQL and InnoDB. I understand SQL's power, but I also understand how constraining it is, not only on data representation, but also on querying. I want to read more posts about people trying to build something without it. Redis is one way, but I'm eager to hear about others.

I wish the author good luck, and encourage him to write another post once Screenshotbot reaches the next stage.
