Qwitter

This is my latest addiction. It’s a free service that sends you an email update whenever someone un-follows your twitter account. I don’t know why, but I figure they send you an email when someone starts to follow you, they might as well send one when they leave.

Tweetdeck

Pretty much this is Twitter for those of you with too many ‘groups’ or followers. It lets you break down your ‘tweets’ into separate feeds that you determine. These can be based on a specific topic, affiliation, location or any other attribute you manage to dream up. It’s also an Adobe Air desktop application that’s still in beta, so there are a few bugs from time-to-time.

Twitt(url)y

Here’s a service that tracks all the links posted on Twitter and ranks them based on the number of recent appearances. There are then many different filter options you can run on the list to narrow it down and even an export function to grab it as an RSS feed.

Twitterfeed

Twitterfeed takes any RSS feed and posts it to your twitter account. Made specifically for auto-updating your twitter account every time you post a new entry on your blog, Twitterfeed can easily be used to post new entries from in just about any RSS feed (i.e. baseball scores from espn.com).

EasyTweets

Now here’s a unique new service that’s still in beta and aimed at those trying to utilize Twitter as a marketing tool. With EasyTweets you can manage multiple Twitter accounts, schedule future tweets (i.e. special announcements), post items from your RSS feed and more. It’s still pretty new but is shaping up to be a great utility for managing your brand identity on Twitter.

#Hashtags

#Hashtags are a way to automatically add your tweet to a specific category, for instance lets say I wanted to create a single location for anyone to be able to add to and see what’s being said about NYE09 on Twitter. I would just go and create the hashtag #NYE09 and anytime that a tweet contained #NYE09, it would automatically be added to the hashtag.org website. The beauty of this service is each hashtag has its own RSS feed and usage statistics. To start using hashtags all you have to do is follow @hashtags and anything with a # in front of it will be added to that specific group.

TwitterKeys

These aren’t really a ‘must use’ but they are pretty neat. They’re icons that twitter accepts as valid characters in tweets. To use them, just copy and paste the desired icon into your message box and voila!

TwitterPatterns

A free collection of unique background patterns for twitter. Pretty cool designs to choose from created by the folks from olivemanna.

TwitterMail

Here’s a service that lets you email twitter updates to your account as well as gives you the option to have all your twitter replies emailed back to you.

Twitscoop.com

Here’s a cool new service that monitors keyword density on twitter to show us what the ‘Hot Trends’ might be, or at least what is the most popular topic. It’s updated every 20 seconds and also has a widget & RSS feed for your own personal use.

Monitter

Here’s a brand-spanking-new service that lets your monitor/track twitter for up to three separate terms in real-time. It also lets you narrow the results based on the users location. RSS feeds available as well.

TweetBurner

It’s a URL shortening service that also lets you track how many times people click on your link. Works with both Twitter and FriendFeed.

Twist

This is a cool little tool that lets you compare trends in Twitter through a variety of different graphical methods. It also has the latest “Hot Before” and “Hot Now” terms sweeping across the Twittsphere. This may look familiar because it was used a lot to show the difference in social media mentions that Barack Obama received compared to McCain in the last few weeks of the election.

TweetStats

Graph your Twitter stats including tweets per hour, tweets per month, tweet timeline and your reply statistics.

Twitter Search (formerly Summize)

Real-time searching of what’s being said on Twitter. Each search provides it’s own RSS feed along with the ability to search for specific users (i.e. @brentter). Formerly known as Summize, it was purchased by Twitter earlier this year. One more thing to note, it auto-updates with each new addition your search.

So, what do you use to manage your Twitter account? Tell me on here or by following me at @brentter on Twitter.
