Social Media Eating Up More Corporate Bandwidth

How much social media surfing and video watching do you do at work? Most likely, it's a fair amount, even though you would not likely admit to it. Additionally, corporate IT managers are getting concerned about the amount time workers are spending on social media sites.

According to new numbers from Research Box, in terms of websites visited, Facebook is commanding 7% of all traffic, followed by Google (3.4%) and Yahoo images (2.8%). When you look at the amount of bandwidth consumed, YouTube is sucking up 10% of all corporate bandwidth followed by Facebook with 4.5%.

It is no surprise that workers check out YouTube videos while at work, although the amount of bandwidth consumed for this purpose is quite high. If this bandwidth consumption pattern continues, corporate IT managers are likely to start throttling or altogether block access to YouTube.

Facebook Unfriends Facebook Lite

Facebook is an extremely noisy site. There are many updates from your friends combined with ads, messages, images, Farmville updates and many other elements that can make it a very cluttered site. To help this, Facebook launched 'Facebook Lite' last September. Facebook Lite featured just the stream, profiles and upcoming events.

Facebook Lite was very much a hidden feature. You had to access it directly by going to lite.facebook.com and was always billed as an experiment. However, if you were a fan of Facebook Lite, we regret to say that the service was cut off yesterday.

It was very nice to have a stripped down version of Facebook, especially when the only Internet connection available is a flakey Wi-Fi connection with poor speed. So long Facebook Lite, thanks for the memories!

Small Group Accounts For Majority of Brand Impressions

They say that your friends and family help drive your spending habits. Whether it's where to go on vacation or which doctor to see, you rely upon your social circle to get recommendations all the time. This pattern is magnified online too, according to Forrester with a small group (just 16%) of online consumers generating 80% of peer-to-peer brand impressions on social networking sites.

How do people discover brand sentiment online? Facebook is a huge source, driving 60% of influence impressions, followed by MySpace (18%), Twitter (10%) and LinkedIn (6%). Other types of Internet sites, outside of social networks, drive brand awareness and sentiment too including ratings and review sites, blog comments and discussion forums.

Apparently, there is a group of people who love to share their brand affiliations and affections and a listening audience who desire this first hand knowledge of products and services. Do you base your buying decisions in part by what you read online? If so, what sites help shape your brand awareness?

LinkedIn Launches New Link-Sharing Features

Realizing that social networkers love to share links and pertinent info, LinkedIn is raising their game for link sharing. LinkedIn, the professional's social network, is adding Facebook-style link sharing complete with article exerpts, link re-sharing (like a retweet on Twitter) and a brand new URL shortener.

The new features will be very familiar to Facebook users, who are used to seeing links combined with small excerpts and even an image from the website or article the user is sharing. The link-sharing features are also automatic. That is, when you paste a link into a status update box and click "attach a link", LinkedIn automatically inserts an image and the article excerpt.

You can also assign privacy settings to the articles being shared which allows you to tailor the audience and connections you'd like to share the article with. For example, if you have a real estate article, you can share it with just your contacts in the real estate field.

LinkedIn has been playing catch up to sites such as Facebook and Twitter by launching micro-messaging, applications and now link sharing. It's great to see the specialized professional social network add these features that users are already accustomed to seeing on other social nets they likely frequent.
