More than 50 million people used Twitter last month – an increase of more than 7 million from June, according to new data.

The website, which attracted 51.6 million unique users in July, now outranks the BBC and Craigslist in terms of monthly visitors. It has also become one of the top 50 most popular websites in the world, according to the research by comscore.com.

Meanwhile BBC Online’s controller Seetha Kumar reported in a BBC blog post that the number of click-throughs experienced by the site stands at 10-12 million each month.  The blog, posted as a response to the BBC’s first online ‘open meeting’ on August 14, revealed that users were dissatisfied with BBC Online’s use of external links.

Kumar said: “We want to establish new and richer connections to the wider web where they are editorially relevant and meet our public purposes. We know that our users want us to do this and it’s a process that we take very seriously”
