Yesterday, Twitter, the microblogging site, rolled out their updated page and introduced new features dubbed as Fly.  It’s a major upgrade for their web and mobile presence, looking to improve the user experience with limited tweets and better discovery tools.  This is the second overhaul for Twitter this year, but while the earlier update ushered in a new design, this week’s update is much more telling of Twitter’s purported business model–that of social discovery and advertising.

From the Twitter blog:

“Today we introduce a new version of Twitter. We’ve simplified the design to make it easier than ever to follow what you care about, connect with others and discover something new. You’ll see this new design both on Twitter.com and mobile phones, so that you’ll have a familiar experience any time, anywhere. We’ve also updated TweetDeck to be consistent with this new version.”

“We’ll be rolling out the redesigned Twitter over the next few weeks. You can see it immediately on the just-updated versions of mobile.twitter.com, Twitter for iPhone, and Twitter for Android. You can get early access on your computer by downloading and logging into Twitter for iPhone or Twitter for Android. We’re working on updates for other apps, such as Twitter for iPad, and will share news as they become available.”

“What we’re announcing today is just the beginning. We now have a framework in place that we will quickly build and iterate upon to help users connect with whatever is meaningful to them.” – #letsfly

The new Twitter features four new tabs, well actually five, if you count the revamped Tweet tab.  The tabs provide a much simpler interface as well, making things easier for users.

Let’s Fly Twitter Tabs

• Home is where you view Tweets from the people you have chosen to follow. It’s your personal collection of Tweets, featuring the latest news, commentary and information from the sources you care about.
• Connect is where you get in on the conversation, where you see who has followed or mentioned you, retweeted or favorited one of your Tweets, and it keeps the conversation flowing.
• Discover lets you tap into a stream of useful and entertaining information, customized just for you, you’ll see results reflecting your interests—based on your current location, what you follow and what’s happening in the world. As you use Twitter more, Discover gets even better at serving up more content just for you.
• Me is the new profile section that puts you and your interests front and center, where you can stay current on your direct message conversations, and it provides you the opportunity to introduce yourself to the world.
• Tweet, the revamped button lets you share anything you want: upload photos, add your location and link to videos, news stories and more, no matter where you are on Twitter.

The enhanced profile page makes it easier for companies to market their brands.  The Promoted Tweet on the profile page will appear auto-expanded making it easier for visitors to see photo or video content that you link to from your Tweet.

But the new updates caused problems for some Twitter users as they experienced limits in posting tweets.  The updates comes with a new guideline that imposes a 1,000 tweet limit per day, as well as having an hourly tweet limit.  The guideline did not mention how many tweets could result in having your account blocked.
