What sort of unlikely coincidences have you experienced on the internet?

Was searching for a cultural reference and the first result was a forum post from 2002. Upon closer inspection, it was me, as a young teenager, chiming in on a topic I knew very little about. I had no recollection of this discussion but was surprised to see that my 12-year-old self was discussing was is still relevant to me 16 years later.

Has anyone else experienced these type of strange, internet-is-forever coincidences?
