Ask HN: How to build effective website to attract early adopters

Hi HN, I started my side project 6 months ago. After developing for 6 months, I feel confident it is ready for some beta users. I would very much appreciate any contributing critics on my WIP website: www.superusapp.com

A bit intro to my project: I started with the idea of connecting all web-based apps and content in a canvas app. Two core features of my app: 1. you can put a browser tab on a canvas; 2. you can move data really easily cross-app.

The primary and secondary titles of the website: Primary: Get Your Work Flowing Secondary: Streamline your cross-app workflow in a visual space.
