No One Likes Stale
Imagine you go to an author website. There you find a bio that talks about their writing experiences, their love of horseback riding, movies, and hats. You also find a list of their books with cover pictures and descriptions. You also find a link to send them an email. What are your impressions?
Now imagine that you visit that same website. In the news section it lists several upcoming book signings from 2008. You go ahead and read the bio. On the bio page it has a section with movie reviews it currently lists Indiana Jones and Wall-E. What are your impressions?
If you decide to put time-sensitive information on your site make sure you keep on top of it. Otherwise, stick with the information that won't go stale quickly.
