TweetDeck’s competitor, Seesmic Desktop is as good as the granddaddy of Twitter clients for Windows and Mac. It utilizes Microsoft Silverlight, is completely cross-platform (which means it can be installed and used on both Mac and Windows OS) and supports all popular social networks and can handle multiple Twitter accounts. The beautiful translucent design and well-spaced tabs makes the app attractive and less cluttered.
Since its development, Seesmic has integrated several social networks to provide a streamlined social networking experience to users. Besides LinkedIn, Facebook and Twitter, the app supports MySpace, Ning and other social networks.
Seesmic Desktop has a simple interface and is suitable for non-geeks who are using a Twitter client for the first time. However, this Silverlight app consumes more RAM and hence will perform slow in low-end PCs. Even with the best graphics card and CPU, the app has shown to be quite sluggish. If you are not comfortable with the slow performance of the desktop app, switch to Seesmic Web, which easily launches on your browser without downloading any third-party application framework.
Using Seesmic Desktop, Twitter users can run multiple accounts effortlessly. They can also view direct messages, mentions and replies for each account separately. The interface can be customized by choosing different view modes and adding various color shades to the background. While the customizable options are few, the interface is sleek and user-friendly.
Improving with every new update, Seesmic has also released a native client. You need to have .NET framework 3.5 installed on your PC before you can install this application. While Seesmic Windows is faster than Seesmic Desktop, there may be some glitches as the app is in beta testing phase.
