Usability — the date is very important

What is with website articles and blogs not putting the date on their work! I find this so frustrating. The article will say something like “Company ABC just released XYZ 3 days ago” Okay, 3 days ago when? Many posts become useless without a date and it affects the usability of your site. It’s great to have archives of everything ever published, but with time some of it will become dated… pun intended. This information may still be of use to some people, but for many it will not. Don’t annoy your users — date your work.
