1. Klout – Klout is fast becoming the Twitter application of choice for how influential someone is on Twitter. Anything over 40 is fairly respectable, but anything over 60 and this person is a major player on Twitter. Klout is one of the best tools to measuring your influence.
2. Grader – Twitter Grader awards you a grade out of 100 for how influential you are on Twitter. This grade appears to be heavily based on the number of followers you have, but it’s very useful for seeing who are the major Twitter players local to you on Twitter.
3. TwitterFeed – TwitterFeed is a great and free application which will automatically tweet out to both Twitter and/or Facebook when you – or another person whose blog you like – has posted up a new blog post. To make it seem like you have retweeted their blog post, add the prefix RT: @name
4. Tweet Spinner – Tweet Spinner has a free version and a pro version ($15 a month). TweetSpinner allows you to schedule recurring tweets, and bulk upload long lists of tweets, rather than writing and scheduling every single one. TweetSpinner also has some neat automated following tools, such as “mimic follow” – which will follow other people’s followers. A little sneaky, but a great tool.
5. SocialOomph – SocialOomph has very similar capability to Tweetspinner, but it does it for double the monthly cost – $30 per month.
6. Tweetdeck/Twitepad for the iPad – Both Tweetdeck and Twitepad are very similar Twitter dashboard tools for your iPad. What they allow you to do is to take the lists that you’ve created and put them (and custom searches) in vertical columns, allowing you to keep up with multiple conversations from the people you want to keep close to. Tweetdeck is free, but Hootsuite (which costs XX) has better capability for handling teams of people using Twitter and multiple accounts.
7. Dabr – Dabr is the best Twitter app for Nokia phones.
8. Twitter for iPhone – Twitter for iPhone is Twitter’s own-brand app for the iPhone.
9. Twitter for Android – Twitter for Android is Twitter’s own-brand app for Android phones.
10. Twerpscan – Twerpscan is a great tool to clear away the people you follow who have stopped tweeting, but it can be a little slow.
