Yahoo! Messenger has long been one of the world's most popular IM clients, mainly because Yahoo! itself is such a large presence in the realms of web-mail, communities and so on. It now sits comfortably in second place to Windows Live Messenger in terms of user-base.
Among the new features in Yahoo! Messenger, the emphasis is very much on looks rather than functions. For example, the brand new IMVironment feature (which completely customizes your chat windows) looks pretty impressive at first until you realize that nearly all of them are simply complex advertisements or marketing campaigns from firms like Gatorade and Kleenex. Improvements to the way contacts' images are displayed, as well as new photo-sharing via the excellent Flickr are welcome additions but even they can't dispel the bad smell emanating from IMVironment.
New emoticons have been added to this latest version of Yahoo! Messenger, as have new skins for the main window. To me, these represent fairly minor aesthetic changes rather than important new functionalities, and as such aren't enough of a reason to upgrade. More handy features like improved handling of PC to PC calls, MP3 voicemail, and better integration with Yahoo! sites have also been included but again, none except for the Flickr tool seems really useful. Really, this Beta feels as if it's about matching Live Messenger for features and not much more.
Yahoo! Messenger probably isn't aimed at users like me who prize usability and simplicity above bright colors and lots of advertising. If you like the sound of branding every chat window you use with Kleenex or Axe deodorant then Yahoo! Messenger is for you. If you'd rather use a simple, elegant and uncluttered chat interface, switch to Google Talk and you'll never look back.
A bloated, brightly colored IM client packed with advertising and not much more.
