For the final 11 days of 2011, we’re going to take a look at some of the top mistakes made this year in our industry… including social media, marketing, branding, graphic design, web design and SEO.

#7- Secret Service needs Twitter training

We’re on a roll of miss-tweets, we promise this is the last one! It’s just that social media is so easy to use, which means it’s easy to make mistakes!

This spring, someone who obviously had access to the United States Secret Service Twitter account (yep, the serious-faced presidential body guards are on Twitter) complained about having to work with crews from the conservative-leaning Fox News.

According to this CBS report, the Secret Service claimed the tweet was from someone in control of the account but who failed to understand that it was going to be public. The tweet was removed, but not before being retweeted. A lot. Oh, and the person who has a complete lack of understanding of Twitter no longer has access to the account.

 Lesson learned: only let those who understand social media represent your company using these platforms.
