ExecTweets.com: “Find and Follow Top Business Execs on Twitter” See FT column by Lucy Kellaway. She says “I think it is potentially the best communication tool there is; the trouble is that most executives are making a complete hash of using it.”
HootSuite.com: if you prefer a web-based way to track tweets + allows you to do something really important - post-date your tweets (ie, put ‘em on a timer) + allows you to manage multiple Twitter accounts + previews a short link before you click
TweetDeck: a downloadable program that lets you keep track of a range of tweets and arrange them into groups
TwitBin.com: a Firefox extension that gives you a sidebar full of live tweets.
Flock.com: a version of Firefox that’s optimized for social media - get tweets, Facebook updates, YouTube videos, Flickr photos, etc, instantly, while never leaving Firefox
Tweetlater.com: offers variety of tools, including, of course, ability to tweet later, along with auto-follow (be careful how use that feature)
TwitterForBusyPeople: lets you see who’s tweeted recently among your followers - or anyone else’s followers.
The true power of Twitter is the retweet (the open nature of Twitter means that no matter how small the group that first sees a tweet, the actual potential audience is millions, depending on the RTs; see #5 here - "10 Most Extraordinary Twitter Updates" by @BenParr).
Learn to use it generously to share other people’s ideas.
If others RT your work often, you will spread your ideas, build your brand and your influence.
Don’t make it a popularity contest. My rule: Don’t worry about the number of your followers. Instead see if you can KEEP the followers you do have - and avoid the churn that you seen on almost all accounts.
