Ask HN: How to show value of an analytics platform for dev and ops?

I'm part of a relatively new startup (jut.io). We're building an analytics platform focused on ingesting operational data (logs, statsd metrics, collectd, alerts). Our secret sauce is a dataflow-driven analytics approach that works really well for both live and historical data. We believe our market is code-centric ops people and developers who also do ops.

Currently our strategy consists of:

(1) Hosting an online playground where anyone can use our dataflow language/visualizations without deploying anything (http://www.jut.io/play);

(2) Showing common use cases in action in that environment;

(3) Creating content showing examples of how you might use us.

My question:

What would convince you to sign up to beta a product like this?
