A politician in the UK literally paid the price for underestimating the power of social networks, after making a charity pledge on Twitter.
Member of Parliament (MP) Fiona McTaggart ended up donating £14,268 ($21,626) to the charity, after pledging £1 for every retweet of her original message.
The MP later admitted she was unprepared for the level of response to what was a spur of the moment post.
