Not the Twitter you're used to: BETTER


YF doesn't look & feel much like any other Twitter client, and that's good. YF is uncompromisingly a MacOS X desktop application, not a mimic of the Twitter website or a smartphone app. As such, it has a highly flexible and functionality-focused UI that is not (at least by default) as cute as it might be, but which works well. If you *want* a flashier look, it has an amazing depth of configurability, easily found in the Preferences dialog where it belongs. YF also offers a rare wealth of functional features (such as versatile types of "muting" and user-defined tabs) that compare favorably to most commercial Twitter clients & outshines Twitter's own clients (including TweetDeck.)

The only caveat for YF is that Twitter has made it quite clear that they dislike the idea of 3rd-party clients, and are particularly opposed to clients like YF that provide tools for users to shape the content of their tweetstreams and the ways tweets appear. YF would be an obvious first target if Twitter actually starts enforcing the UI rules they have published for client apps using their API, and the way their API works provides them the power to disable YF (or any client) unilaterally.

A Fantastic Twitter Client for the Twitter Addict


I have been using this client for a bit over half a year now and have loved it since the first day I started using it. It is highly customizable and has the perfect balance between a simple interface and “geeky” flexibility. I love the fact that while working with Growl to provide notifications, it also alerts the user with different sounds, the volume of which can be adjusted within the app. I also appreciate the plethora of keyboard shortcuts available for quick switching between Timeline, Mentions, ETC, performing actions on a tweet, and switching to other areas in the app. The new addition of support for multiple accounts is great for those who maintain several accounts (including keyboard shortcuts to jump between accounts). Last, but not least, I appreciate the attention that YoruFukurou developers have given to compatibility with VoiceOver.

If it isn't obvious already, I highly-recommend this app and feel that its feature set is rich and satisfying for any user who wishes a clean, feature-packed client interface to Twitter.
