As Facebook floats on the Nasdaq, cynicism remains over the third largest initial public offering (IPO) in United States history, after Visa and General Motors.

The social network offered over 400 million shares at €38 (£31) each in its IPO on 17 May before the main flotation on 18 May. Mark Zuckerberg's social network will raise $16 billion in its first offering, making it the third-largest IPO in US history and by far the largest technology IPO ever, dwarfing the $1.67 billion (£1 billion) of Google's 2004 offering.

Micro-blogging site Twitter is to start recommending users for you to follow, based on your recent web browsing history.

The site calls these " tailored suggestions," and it will track your footsteps across the web by using integrated Twitter buttons and widgets as surveillance outposts. So, every website with a "Tweet this" button will log your visit.

Then, the social network can recognise which accounts are frequently followed by people who visit popular websites, and recommend those accounts to others who have visited those sites within the last ten days.
