Here's a quick snapshot I took moments ago:
And here are the dates of those stories:
1. 21 February 2010
2. 15 June 2010
3. 19 February 2008
4. 5 November 2009
5. 18 April 2006
So, two stories from 2010, one from 2009, one from 2008 and one from 2006. I'm sure that the BBC is doing the ranking correctly. People undoubtedly are sharing those stories. But how useful is this list?
The final story Blair defends higher GP salaries is four years old. It dates to when the Labour Party was in power and to when Tony Blair was Prime Minister. But what's the relevance today?
The story Feeling grumpy 'is good for you' has in recent weeks appeared many times here. Sure, it's a reasonable story, but do we need to see it all the time?
I suspect that the BBC's algorithm is taking into account just raw share numbers and social networking effects are pushing up these stories to the top 5.
A better default would be the "Read" tab not the "Shared". It reflects current news much better.
