Found something I wrote in 2009, when Yahoo shut down Geocities:
"It’s funny: the things we expect to disappear from the web often don’t, but the things we expect to be permanent often do drop out of existence. GeoCities appeared 14 years ago. Will today’s blogs, Facebook pages, forums, and wikis still be around 14 years from now?"

The blog I posted it on is still there. A lot of sites it linked to aren't.
