Facebook has a huge value to UK business.
As someone who deals with eCommerce every day in my work the businesses who are good at social media (including Facebook) are the ones who are doing well online.
The difference between Facebook and it's predecessors is that Facebook came at the right time in the eCommerce evolution.
One Facebook "Like" on a corporate page is worth much more to an eCommerce business than a lot of other marketing. It gets it boosts in it's Google rankings along with all the other Facebook associated public data held on you.
Even small businesses who can barely afford it are spending thousands of £ a month just to keep their standings in Search engines, and Social Media plays a huge part in that.
Everytime a company is asking you to "Like" their Facebook page it's much more than you just being able to see their posts and product updates. That like, in real money terms, can be worth more than £50 out of a Marketing budget.

Facebook can only be good for Mayhem.
From a personal point it means, because I have Facebook on my phone, I can keep up to date on things while sat on the Toilet or in particularly boring meetings where looking through a forum might be frowned upon!
