I have seen people trying to promote their blog posts randomly without considering the different time zones in many countries around the world.
Just sending out tweets, submitting diggs or sharing on facebook won't do it and will be missed by a huge amount of people.
If you want the highest possible exposure of your new blog posts considering the different time zones is crucial.
I have experienced that promoting a post globally and most effective should be done at:
5 'o' clock pm London time (Beer time)
equals
6 'o' clock Germany, France etc. ( Dinner time)
equals
9 'o' clock in Silicon Valley (arriving at the office)
equals
12 'o' clock in New York (Lunch time)
In order to reach our Australien and Asian friends you have to promote your blog post again around 6 - 9 hours later.
Check out this time zone world map:
Since you are not always availabe, there are some really great tools to schedule your tweets such as twitterfeed.com or tweetlater.com to gain the highest possible exposure.
