#1. HootSuite : In my past post about the web app, you will notice I have a real attraction to the User Interface. Its so easy to manage your Twitter account in the HootSuite interface by scrolling left and right and inputing your message. Also, there is a feature to watch keywords used by users on Twitter, this is great to keep track of trends.

#2. Ow.ly : This is a URL shortener for those long-pesky URLs. This also works with HootSuite to keep track of your click-throughs. What an excellent way of seeing what your followers like and dislike. Don’t be afraid of the URL shortener, its good.

#3. WeFollow : This is the best Twitter directory out right now. There are a few other directories that are good but not great. Sign up is easy: Username, Password, Keywords and submit. Now when someone searches a keyword on WeFollow your username will appear on the list. You are ranked by followers or influence. So, go and get noticed!

#4. Twitpic : Submit your pictures and share! This is an excellent geo-tracking web application that works like flickr but its just for Twitter. This also places a geo-tag on your photo so it can be found by region, city, or town.

#5. Friend or Fellow : Do you have trouble finding the people who you are following but they’re not following you? This is the web app that will easily make the list of people that are not following you, so you can either suggest that they follow you or you can remove them from your follow list. Twitter has a give/take etiquette and if you follow someone they should follow you back, but you can use Twitter how you want because I follow about 50 people that will probably never follow me back.

That is it! Let me know what you think of the list…
