First up, thanks so much for all of the work on this. I've long watched (and used) this project wondering if the community would eventually converge on TSLint or ESLint for checking TypeScript code and am really excited to see the recent progress on this project.

Once this project hits 1.0 it would be interesting to benchmark it against TSLint on some largish codebases. This would not only help people in deciding which to use (although speed is only a minor concern IMO, number and features of rules and community adoption would be more important to me) but it could also potentially help find bottlenecks in different rules.
