If you’re like most people, your permalinks (the permanent links to individual posts) probably look like this:
yourdomain.com/2015/02/24/title-of-post
We’re all familiar with those URLs. The date of the post is explicit, so you need never wonder when it was written, or how recent it is.
Here’s the thing, though: they’re horrible.
Agreed. To me, the permalink structure is as a part of the design. That said, there are sometimes reasons for dates, or at least numbering, in permalinks. They’re used by services such as Google News. That’s not an excuse though.
