I have been using stackoverflow for a while, coming in from google without logging in. The content is truly helpful.
The worst part about the site, though, is the usage of "time ago" instead of a real datestamp. It is maddening to know that, for example, software X was released on Y date [ie YYYY.mmdd format] and have to mentally compare the Stackoverflow unformatted date [ie such as "6 months and 5 days ago"].
A number of us seem to consider this a bug, but I did not see my specific problem scenario described. So, in hopes of change, here it is!
There are a few related questions here, such as: See Add year to question and answer dates .
