This week, it was Twitter's turn to make news, while LinkedIn served up another update.

Can Login Verification Keep Your Tweets Safe?

In light of recent Twitter security breaches and incidents Twitter released a new security feature -- login verification. Announced in April, the security feature is now available. Designed to provide an extra layer of protection, it's two-factor verification makes it so once you log into Twitter, you'll be asked to provide additional information to ensure it's really you. After you enroll in login verification, users will be asked to enter a six-digit code that is sent to your phone via SMS each time you sign in to

While we appreciate Twitter's attempt to secure our Twitter profiles from the likes of hackers and disgruntled employees, it doesn't necessarily take into account how Twitter profiles are used by companies. Most companies have multiple people managing a single account, but Twitter only allows one email address and phone number per account. This means, their new two-form authentication will only work if people are actually logging into the account via Twitter (though you can generate temporary passwords for logins via other applications) and the SMS will only be sent to the owner of the account. 

It's a start however, and perhaps those who decide to opt-out of this verification will be encouraged to be more diligent about how they share passwords so they can keep their accounts better protected. 

Real-Time Video & TV Ad Targeting

Twitter also announced Twitter Amplify, which will bring real-time video into the site. Launched with initial partners by their side, including broadcasters BBC America, FOX, Fuse and The Weather Channel, Amplify aims to provide dual-screen sponsorships and in-Tweet video clips. You may have already seen versions of this in your feed during the NCAA basketball tournament and the NBA finals. 

Accompanying its release is a TV ad targeting tool, the result of Twitter's acquisition of BlueFin Labs in February. With TV Ad Targeting, an advertiser or media buyer can use a special dashboard created by Twitter, through which a brand can monitor when an ad has aired on TV. Considering that more and more brands are attaching hashtags to their 30-second ad spots, it makes sense to give them some way to measure its reach. The dashboard will also track promoted tweets, as well where and when an ad ran on TV and those who have tweeted about the ad as a result. 

Navigating LinkedIn

LinkedIn, following a host of recent updates to its platform, has introduced a new navigation bar to its website this week. This newest update seems to be an attempt to streamline the design and feel of its new mobile app with the desktop version.

We're sure this isn't the last update from LinkedIn, but we're curious to see if these new updates encourage better networking habits of its users, or make them feel like they're using Facebook.
