Ask HN: what are the two best technical decisions you made for your startup?

1. Tackle a hard problem : a) is interesting b) hard to follow

2. Choose a technology stack that will work for our projected scale and that we knew well (hint - may not be pop).

We are having fun and will (shortly) be delivering as much joy as we can manage to our user community.

1. Write our own profiling code: Lots of conventional wisdom doesn't stand up to running your own tests.

2. Use XML/XSL for a rendering/template engine: After 10 years, it is the cleanest and largest part of the code base.

1. To use Emacs

2. To use Vi

Or was it the other way around? I can't remember.
