If you are on Twitter I'm sure you realize how time consuming it can become in a short period of time. Below are some of my favorites, of course there are tons of independent sites. Have fun with the list below and please share some of your favorites.

Below are some of my favorite Twitter applications:
1. Tweetlater.com -- you can use this to monitor for specific words or phrases. They will email you the results (with several different timing options).
2. search.twitter.com - you can look up whatever you want - want to see everything I've ever written? just type in that person's Twitter ID. Want to look for a specific phrase...same thing.
3. Tweetscan.com --- same concept, will look for a specific word or phrase
4. Tweetburner.com - this, by far, is my favorite thing in the entire Twitter world. Sign up for a free account and you can track the number of people that link through. For example: last week I wanted to post a Tweet that drove members to the site to get the free version of QuickBooks. I copied the Intuit link into Tweetburner, then copied that link into my Tweet. I can see now that 27 people clicked through to Intuit's site.
5. Tweetdeck.com --- this is easier to manage than being online at Twitter.com (of course, I hate black backrounds so I had to change the default color settings).
