So, here are my top Twitter applications.

Twhirl (for my Mac)
TweetDeck seems to be the choice of Twitter power users everywhere; I am not a power user.

After trying out a few different apps for my Mac (including TweetDeck), I finally chose Twhirl. Twhirl has all that I need in a nice clean interface. Twhirl allows me to have multiple accounts up at the same time so I can easily follow what is happening in my personal and business tweetstreams. I also like the Growl notifications, which allow me to follow along without having to to constantly switch over to see new tweets.

BirdFeed (for my iPhone)
I have tried five or six different Twitter apps for the iPhone. A while ago I read about BirdFeed on TechCrunch. They spoke highly about the new app so I thought I might give it a chance. I have been using Birdfeed ever since.

Birdfeed has a simple and clean interface, it allows me to easily see mentions/replies, and it provides easy access to retweeting or replying to other people’s tweets. Birdfeed also bookmarks my Twitter time line so I can easily refer back to a recent tweet I want to see. Finally, I like how the interface looks similar to the iPhone texting (or iChat conversations) interface.

Flickr (for sharing photos)
Flickr was a little late to the Twitter-picture game, but I am glad they are here. Facebook and Flickr are the two places I share my photos with the world. Since I am already adding my photos to Flickr, it makes things easy for me to reference my “photo” tweets through them instead of worrying about another website.

FriendOrFollow (for a bird’s eye view of my Twitter community)
FriendOrFollow easily allows me to keep track of my Twitter community. On their website, I have three options. I can see who is following me (with no love in return), who I am following (without reciprocation), and who are my friends (those who follow me and I follow back).

The benefit of using FriendOrFollow is that I have a better idea of who I am actually engaging with on Twitter. The information is used (in conjunction with other criteria) to allow me to make more informed decisions on who I should continue following.
