This is not so much for me, but if you have anything you didn't like about it, I think a lot of people would really like to hear about it. The most negative blog post I've seen on HN was something to the effect of "it wasn't the right fit for me", and it's really hard to judge something critically without getting both positive and negative opinions. From what I've seen of you guys it looks like it was a very positive experience for you though, so I'm not sure this is really applicable.
For myself, I'd say write it if you can think of any related tidbits/stories to tell. Those are always interesting.
