TweetDeck is a free tool by Twitter for Twitter. It helps you manage your Twitter account easily, see who’s followed, retweeted or mentioned you, create lists to monitor competition, monitor hashtags and most importantly, schedule tweets to post in the future. Great time-saving tool!
I first discovered TweetDeck when I was trying to manage an employer’s Twitter account as well as my personal one (because I was promoting a book). I was switching back and forth having to log out of one to log into the other. I also needed a way schedule tweets to out in the future. (Twitter’s up 24/7, you don’t have to be!)
