Not interested in a multipronged app that supports numerous social networks? Consider A.plus, a Twitter app from Hollywood's Twitter king, Ashton Kutcher. Developed in conjunction with UberSocial, Kutcher's A.plus app offers a decent set of features, such as the ability to view Web-based content directly within the app via its LivePreview panel. Be warned, however: If your tolerance for all things Ashton Kutcher are low, you may quickly tire of the app's A+ panel, which provides easy access to Kutcher's Twitter feed as well as that of his soon-to-be-ex-wife Demi Moore, along with a few feeds of his choosing. You can hide that panel--but if you do, you might as well use something else.
If you're seeking a dedicated Twitter app that's light on celebrity influence, consider Blu. Developed as a concept application for Windows 7, Blu is certainly slick. It's more than just a pretty face, though, as this Twitter app lets you easily view your Twitter timeline, @ mentions, favorites, retweets, and more.
If you're finding Twitter a bit overwhelming, give PostPost a try. This free service helps you dig through the chaos of Twitter to find content that's personally relevant. PostPost's latest version includes a new Timeline Topline feature, which pulls in the topics, links, photos, and videos from your Twitter timeline that are most appropriate for you. The service determines what's relevant by examining your Twitter account and how you use it. PostPost artfully arranges some of the Twitter content you most want to see--and even stuff you didn't know you wanted to see.
Another service that's designed to help you dig through the boatloads of information on Twitter is Tweetmeme. It does the job by collecting what it deems to be the hottest links on Twitter, and presenting them to you in an attractive layout. Tweetmeme is easy on the eyes, and quite simple to figure out, as it clearly tells you how many times a link has been tweeted, but its usefulness is limited due to its emphasis on links and only links.

This online directory service, which bills itself as "The World's Largest Twitter Directory," lets you list yourself so that potential followers can find you more easily.
