Enough “meaningless drivel”. That's the message from a group of members of the UK government who have been examining how social media firms like LinkedIn gather and use social media data.
The House of Commons Science and Technology Committee's report, released last week, has blamed firms for making people sign up to long incomprehensible legal contracts and calls for an international standard orkitemark(认证标记) to identify sites that have clear terms and conditions.
“The term and conditions statement that we all carelessly agree to is meaningless drivel to anyone,” says Andrew Miller, the chair of the committee. Instead, he says, firms should provide a plain-English version of their terms. The simplified version would be checked by a third party and awarded a kitemark if it is an accurate reflection of the original.
It is not yet clear who would administer the scheme, but the UK government is looking at introducing it on a voluntary basis. “we need to think through how we make that work in practice,” saysMiller.
Would we pay any more attention to a kitemark? “I think if you went and did the survey, people would like to thinkthey would,” says Nigel Shadbolt at the University of Southampton, UK, who studies open data. “We do know people worry a lot about the inappropriate use of their information.” But what would happen in practice is another matter, hesays.
Other organizations such as banks ask customers to sign long contracts they may not read or understand, but Miller believes social media requires special attention because it is so new. “We still don't know how significant the long-term impact is going to be of unwise things that kids put on social media that come back and bite them in 20 years'time,” he says.
Shadbolt, who gave evidence to the committee, says the problem is that we don't know how companies will use our data because their business models anduses of data are still evolving. Large collections of personal information havebecome valuable only recently, he says.
The shock and anger when a social media firm does something with data that people don't expect, even if users have apparently permission, show that the current situation isn't working. If properly administered, a kitemark on terms and conditions could help people know what exactly they are signing up to. Althoughthey would still have to actually read them.

阅读下列短文：根据短文做出正确的回答。

       Walking will be banned on escalators as part of a trail designed to reduce congestion(拥堵) at some of the country's busiest stations.

        In the first move of its kind, all travelers will be forced to stand on both sides of escalators on the London Underground as part of a plan to increase capacity(容量) at the height of the rush hour.

         A six-month trial will be introduced at Holborn station from mid-April, eliminating the rule of standing on the right and walking on the left. The move, imitating a similar structure in Far eastern cities such as Hong Kong, is designed to increase the number of people using long escalators at the busiest times. It could be expanded across the Tube network in coming years.

     According to London Underground, only 40percent of travelers walk the full length of long escalators, leaving the majority at the bottom as they wait to get on to the “standing “side.

       A three-week trial at Holborn last year found that the number of people using escalators at any time of could be raised by almost a third. Peter McNaught, operations director at London Underground, said: “It may not seem right that you can go quicker by standing still, but our experiments at Holborn have proved that it can be true. This new six-month trial will help us find out if we can influence customers to stand on both sides in the long term.”

      Holborn has one of the longest sets of escalators on the Underground network at 23.4high. Tube bosses claim that capacity was limited because so few people wanted to walk up—meaning only one side was used at all times. Research has shown that it is more effective use of escalators over 18.5 to ban walking.

      The previous trial found that escalators at the station normally carried 2,500people between 8:30 am and 9:30 am on a typical day, rising to 3,250 during the researching period.

      In the new trial, which will be launched from April 18, one of three “up” escalators will be standing only, with a second banning walking at peak times. A third will remain a mix of walking and standing.
