Twitter continues to herd users towards a web-only interface. In a blog post, the Tweetdeck team announced that Twitter (which owns the app), is discontinuing support for Tweetdeck AIR (the desktop version for OS X and Windows), Tweetdeck for iPhone, and Tweetdeck for Android, and will stop distributing them in “early May.”

Back in October, Tweetdeck was overhauled with a new design and personalization options. The app’s Chrome version was previously updated with some nice features such as “Embed this tweet,” and now all those new features have been brought into Tweetdeck for Mac.

Would you pay as much for a Twitter client as you would for a copy of Mountain Lion? I did, for a copy of Tweetbot. I’m a huge fan of their iOS client, and after Twitter bought then gutted the beloved Tweetdeck (as they did with their iOS app), I was really excited to learn that Tapbots was developing a OS X client. Tweetbot for iOS is a full-featured, user-friendly app, and its big sister on the Mac matches its features.

Evernote will soon release a redesigned OS X client adding a number of user interface improvements and changing a few elements inside the app. The developers stated on the official Evernote blog page that the update brings an impressive 100 new features to the app.

Microsoft has released Skype v.6.0, adding a few improvements and bug fixes. The update adds Retina display support for Apple’s latest MacBook Pro laptops and also brings richer integration with Facebook, allowing you to sign in to Skype using your Facebook account information. Microsoft also has added chat protocols that give you the choice to chat with friends using their own Windows Live messenger.

Fans of Twitter’s social services will find this news a bit disheartening; according to a new tweet from TechCrunch’s M.G. Siegler, Twitter has decided to stop future development of the free Twitter app for OS X. For now, users will still be able to download the Twitter application which was launched on the Mac App Store in 2011.

The official Facebook Messenger client has made its way onto Windows after being released on iOS last August. OS X will soon be seeing its version of the app as well; the company confirmed Facebook Messenger for OS X is currently in the works although, although they declined to give an ETA. If you’re on an OS that is currently unsupported by the official Facebook Messenger, there are plenty of third-party options that give you access to Facebook messaging, from Adium on OS X to the cross-platform Pidgin.

64% of women admitted to an Internet addiction, compared to 55% of men. Internet addiction was present in every age group, but younger voters were more likely to be hooked (73% of those between 13-17 and 71% of those between 18-24). The numbers decreased for older respondents, with only 39% of those between 55-65 admitting to the addiction.
