This makes me wonder if Google makes the internet susceptible to losing rare data. It's possible that the only solution to your OpenSolaris error 16 existed in a web forum that existed until only recently. If Google didn't exist (and people couldn't find the answer), it's plausible that more questions/answers on this topic would have existed.

Then again, you could always create a new post on your problem in the hopes of attracting the attention of someone who solved your problem, but I still wonder if Google unintentionally promotes knowledge-scarcity.
