Yes, and it's comforting to know that even these people need to look up UNIX flags from time to time! Not really surprising, but a bit reassuring nonetheless.
That actually happens to me from time to time and I've learned to look through my own blog posts for answers before venturing out.
However, the worst situation is when I google for answer, find that ONLY my own blog post has something relevant and it doesn't answer exactly what I need -.- at that point, I'm like, "Google, I wrote this, I already read it, why don't you have something better to show me?"
