Evergreen, now there's a euphemism. :-)

I appreciate, in the end you have to do what gets you the most views, however, from my perspective missing out the date means you prefer to waste my time as I have to scan the article until I get a feel for how old it is.

I would read anything written within 6 months and would consider up to 12 months if the information was high quality. It's not like we're overburdened with quality, independent, information.

If your going to be business minded, why not have the date on for the first few months and remove it when the first flush of green has gone. ;-)
