Question: [This question about the sun's circumference](https://physics.stackexchange.com/questions/68120/how-is-suns-equatorial-circumference-measured/68125#68125), I answered with what I *thought* was a helpful answer - it seems that a couple of others found it useful (2 upvotes), but I am getting grief about the answer being "while strictly correct, but is enormously unsatisfying".

Why not then, if an answer is "enormously unsatisfying", post n alternative answer?

What have I done wrong this time?

Answer: 
I can only repeat what I wrote before.

1. Your answer is strictly correct.
2. But you have assumed the hard part of the historical problem has already been solved and answered with a basic geometric identity so I found your answer to be uninteresting.

and emphasize that 

* I did not vote your answer down.
* No one else had voted your answer down.
* A couple of people had found it useful enough to vote up.

Finally, I'm having a hard time understanding how you get from a +2/-0 result on an answer to understanding that you have "done [] something wrong" or "stuffed up". You are ahead with that answer and there is no reason to expect that you will ever be behind---the answer is correct as far as it goes.

Initially being too sensitive to fair, constructive criticisim of your answer, that replaced one measurement with another, without explaining how the new measurement was to be carried out.

What did you do right?

Taking on board the criticism in the comments and improving the answer.
