This is one of my favourite xkcds because it made me more consciously aware of the peculiar intimacy of the situation in the comic. Furthermore, in addition to the link that exists between me and someone on a forum with my particular tech problem, it also made me feel connected to everyone who had a different problem to me, but were also desperately trawling forums for help
This comic made me go back to a post I made and put in the solution I found to a really strange problem. 2 years later someone responded saying they had the same problem and my solution fixed it for them.
