7. Twitterfone
Twitterfone is a nifty tool which let's you post messages to your twitter account using your voice. It translates your voice into text and posts them. You can use it when you don't feel like using your cellphone's keypad to tweet.

8. Twittercal
Twittercal, as it says, connects your Twitter account to your Google Calendar account and let's you easily add events from twitter.

9. Quotably
Quotably let's you view the twitter conversations as a discussion thread and also allows you to reply to them and participate in the discussion. This can be very useful if you are looking to follow a particular discussion.

10. Timer
Last but not the least, Timer does a very simple but extremely useful thing. It uses twitter to remind you about a task at the time specified so that you don't forget to accomplish it.

I hope you'll find all or some of these tools useful as a twitter user. You could also follow me on twitter.
