Joining her husband on Twitter, Michelle Obama has started to tweet this week amid a warm welcome from the White House. However, the First Lady used a proxy account, rather than creating one of her own, to interact with the Twitter-sphere.

The White House made a pretty big deal of Mrs. Obama sending her first tweet, but they neglected to do one thing: set her up with her own account.

Michelle sent a tweet from the @JoiningForces Twitter account earlier this week. She wrote a message of support for military families:

Military families serve our nation too. Let’s all show our appreciation by #JoiningForces with them. Get involved: –mo

The tweet, signed “mo”, shows an impressive use of hashtags for someone so new to Twitter, so kudos to the First Lady!

Along with this tweet, the White House released a video showing Mrs. Obama using he Mac to actually send the tweet. The Twitter newbie comments, “So this is how you tweet, huh?”, and after typing she asks “…so now I just press tweet?”, a little unsure if that’s all there is to the process (it is).

It’s great that Michelle is familiarizing herself with Twitter, but I think it’s time she sign up with her own account. She’d be following in the recent footsteps of fellow wife-of-powerful-leader-and-equally-powerful-woman Melinda Gates, who signed up just a few weeks ago.

After all, President Obama is among the top 5 Twitter users in terms of number of followers, with over 10 million to his name. I’m sure he could give her a little recommendation and she’d quickly see followers pour in by the thousands. And judging by her use of hashtags and links in her very first tweet, she’d be a natural.
