Twitter has a problem: A number of users tweet, then lose interest. It needs a way to reengage them in the site. And tonight it’s starting to test one way: Notifications.

The test is currently only rolled out to a “limited” number of users right now, according to this update. But those who have it should notice an indicator similar to what Twitter does to let you know there are new search results on a query (see a capture above and below). There’s another service that does these types of notifications for new messages also: Facebook. Yes, Twitter for once is taking a playbook from its rival rather than the other way around.

When Twitter was still a young service, it used to auto-update with new tweets as they came in, in realtime. That was one of the first features killed off as the service began to explode in size and was having trouble scaling. FriendFeed implemented a similar live-updating stream before the Facebook acquisition, and that seemed to help boost engagement. Twitter currently offers live updating stream with its widgets.

The new, revamped MSN homepage is now live. Updated on Tuesday, November 3rd, this hugely popular internet portal sees 100 hundred million visitors per month who comes to read news, watch videos, and get other local information like events and weather. Yet despite its popularity, the portal has not seen a major overhaul of its design since 2004.

If you’re not a regular visitor to the site, you’ll still be able to tell at a glance that it’s undergone a number of big changes. Nothing has been left untouched – even the butterfly logo has been revamped!The new site opts for a much cleaner look. Gone is the blue background surrounding the white space, replaced by a completely white background instead.

At the top of the site, there’s a Bing search box, followed by topical links underneath taking you to news, entertainment, sports, money, lifestyle, or “more” subsections. On the main page, the lead stories are promoted by large, attention-grabbing images while other news items appear below as links.

A new diet on Twitter dubbed Tweet What You Eat has been hailed for its effectiveness as it shames people into listing the amount of calories they have consumed each day.
The diet on Twitter is being used by celebrities including Stephen Fry, who has reportedly lost six stone in six months, and Little Britain star Matt Lucas, who says he has lost half a stone in a fortnight.

Tweet What You Eat is an online food diary that allows you to instantly enter everything you eat. The application, which already has more than 8,000 followers, has a 'CrowdCal system', a completely crowd-sourced calorie database, which fills in food entries' calorie count based on what other members have entered. It allows you to keep track of your weight to see if the diet is working while there is also a forum for dieters to discuss food.
Alex Ressi, creator of Tweet What You Eat, said: "People need to be able to share in the success and lean on others.

"I've had people write in and share stories about 20 pound, 40 pound and the most dramatic – a 70 pound weight loss using the Tweet What You Eat tool and working in conjunction with a nutritionist."
