Hillel Fuld (you can follow him here) posted a fantastic article about the basics of Twitter. Included in his article was a handy reference guide to Twitter terminology. Here are the terms you need to know in order to make use of Twitter in the most efficient way:

8. TwitterFon: I would love to somehow check the correlation between Twitter users and iPhone owners. Judging by the frequent iPhone trend on Twitter, a lot of Twitterers use iPhones, so I thought I would let you know which iPhone Twitter app has all the competition beat, hands down. Twitterfon is the number one iPhone app for Twitter in my opinion. I am not going to go into the detailed comparison between Twitterfon and Tweetie, you can read that here. What I will tell you is the fact that Twitterfon notifies you of new tweets, replies, and DMs makes it the app for me, period.
9. Topify: I have discussed Topify before, so I will just say that it is one of the most useful Twitter services out there. It replaces the annoying and useless Twitter emails you get when someone follows you, with a useful and informative email. It also allows you to follow back by replying to the email. Topify also enables you to reply to a DM via email and the best part is that the developers really listen to customer feedback and improve the service accordingly and consistently.
10. Wefollow: I have also discussed this service before, so I will tell you that when my wife joined Twitter, this is the first place I showed her. WeFollow is the best and most effective way of finding people to follow. It is a Twitter directory based on tags people give themselves, and is organized in a very user-friendly way to enable you to build yourself a quality Twitter network in a very short period of time.
