Unwarranted answer deletion
I wrote an answer a year ago to a question about how much power some consumer device uses. My answer was basically to measure it, gave a starting explanation of how to do that, and suggested to ask on the Electrical Engineering site with the results so that they would be properly interpreted. This answer was deleted earlier today.
This was a serious answer. If I were faced with needing to know the power usage of such a device, that's exactly what I would do. I realize that takes some EE skills, which is why I described basically what to do, then explained what to ask on the EE site to understand the results and get the final user-level answer. If the OP had done what I suggested, I see no reason he wouldn't have gotten exactly the answer he was seeking. If the OP didn't understand something, he could have asked for clarification. The fact that the OP did none of these things doesn't make the answer wrong or invalid.
A year later, someone apparently found documentation where you can look up the answer. That doesn't invalidate the existing answer that describes how to determine the information for yourself. The existing answer would still work, and applies to any other device where such documentation isn't available.
I understand the desire to keep the site clean, but this answer was not noise, and would have led to the desired result if followed. The fact that the OP chose not to follow it isn't relevant. I doubt the answer would have been deleted if the OP used it to get what he asked.
This is tagged "discussion" because there are only four tags allowed, and the other three fit even less well. This is really a complaint about moderator action, but a discussion would be useful to see where everyone is at.
