Twitter has just launched a new app refresh for its mobile apps in Android and iOS, as well as expanded its offerings to the Kindle Fire and the Barnes & Noble NOOK and NOOK color.

Returning to the iOS and Android apps is the ability to swipe individual tweets to reveal tweet actions like ‘Reply,”Retweet,”Favorite’ and ‘Profile’ — a feature which was initially available in Tweetie, the app that eventually became Twitter for mobile, and then removed inexplicably. Another blast from the past is the ability to copy and paste text of tweets and user profiles, which I for one really missed.

A significant step for Twitter in its international growth: Yandex, Russia’s search giant, today announced that it will carry Twitter data in all of its search results.

The news also underscores one possible route to revenue generation for Twitter: Yandex describes this as a licensing deal. The terms of it were not disclosed but Microsoft reportedly paid Twitter $30 million for a similar search agreement.

At Apple’s WWDC event last June, Twitter made a new best friend: Apple. The tech giant announced that it would bake the social network into every single iOS device by way of the new iOS 5 software. This left many stunned for two reasons. 1) Apple rarely does such deep partnerships with third-parties. 2) It wasn’t Facebook.

It was all-around a huge win for Twitter. And a win for Apple as well, as it has been proven throughout the years that they don’t get social — a subject which was a topic of debate again yesterday coincidentally. Apple needs to build it’s own social network, Dan Frommer argued! No, they need to get their social platform right, argued TechCrunch editor Eric Eldon. Well, today they’re taking a big step: by doubling down on Twitter.

Confirmed: Apple can still surprise.

On July 20 of last year, Apple began a journey. With OS X Lion (aka OS X 10.7), the company started taking some of what they had learned from iOS, and the iPad specifically, and putting it in their more mature OS. Today, that transition continues with OS X Mountain Lion.

Yes, Apple is already ready to show off the next version of OS X — technically 10.8 — just seven months after the last version was released.

Twitter has posted a seriously awful/hilarious recruiting video to YouTube, which the company says was the product of last week’s “Hack Week.” During this time, employees were able to take time away from their day-to-day work to collaborate on new ideas. Although it was only posted on Friday, the video has already seen over 400,000 views at the time of writing. Why so viral? Because it’s parodying the entire genre of startup recruiting videos by purposefully being bad. Really, really bad. So bad it’s funny. Or at least that’s the hope.

The video has everything: amateurish effects, cheesy music, stilted speech, bad acting, poor production quality, and sayings like: “Man this is a sweet job. But working at Twitter isn’t just a sweet job, it’s a way of life – a way of life that’s like a sweet job.”

Yeah, you pretty much have to watch this one.
