thanks for your detailed blogging about the whole process of going from idea to quitting your job to launch. i spent about 30min going through all your blog posts. very encouraging and real. a great resource for others who are in the same boat.

why the pi?

Balsamiq has come full circle (concept, dev, launch, business).

Then wouldn't it be 2pir, ~6.28 if we assume a unit circle?

I wasn't actually talking about the circumference per se, just that Balsamiq has come "full circle" which I represented using pi.

I know it's just a saying, but taken literally, "coming full circle" would mean the circumference. That is, going around in a circle.

actually, when a circle's diameter is 1, its circumference is π

I think "unit circle" means a circle with a radius of 1, not a diameter of 1: http://everobotics.org/projects/roboMagellan/img/UnitCircle....

How did you do the marketing for Balsamiq? Or is that covered in one of your blog posts?

It isn't, but a few people have asked me the same question, so I might write it up soon. No rocket science...I just followed some good advice: http://www.balsamiq.com/blog/?p=58
