I dislike coming upon writing where there's no date. Because then I can't judge for myself from what context or perspective the author wrote something. (Is the assertion that mobile market is growing in the context of pre 2008 iPhone, or after?)
There's many assumptions we take for granted, even when we try to write evergreen. And sometimes those assumptions turn out to be overturned after a while.
When I happen upon articles, essays, blog posts, etc without a date, I usually trust it much less, and try to find similar information with a date.
The only way you'll know if your writing is evergreen, is over the course of time. I'll read stuff from 2002, and find it's still relevant, but we need to judge whether it is for ourselves every year. And not timestamping it robs us of that.
