This week Cancer Research UK partnered with the Metro newspaper to feature messages from people affected by cancer thanking those who helped them.

Technically this is more traditional media than social media but Spy doesn’t dirty its hands with newsprint and spotted the charity tweeting about it. The paper does encourage readers to ‘join the conversation’ on CRUK’s Facebook and Twitter pages and uses the #GoodDeedFeed hashtag on Twitter.

In a similar vein CRUK has been all over #ThankYouThursday this week and posted a number of messages and infographics thanking supporters on its social feeds. One of our favourites is pictured, and there are more on its Facebook page.

Why we love it: while large charities are, and should be, run on professional basis, they still rely on the goodwill of donors and volunteers who deserve to be appreciated and celebrated.

Donate your social profile for World Humanitarian Day to #sharehumanity

For World Humanitarian Day (19 August) the UN Office for the Coordination of Humanitarian Affairs, which runs World Humanitarian Day, urged people to give it access to their Facebook or Twitter feed and allow a series of posts highlighting others who make a difference.

The campaign was backed by celebrities including Leona Lewis and 172,999 posts were shared in total.

When people agreed to allow World Humanitarian Day to post on their behalf they were able to preview the posts that would be share, including videos and photos, and de-select any that they were not comfortable with.

World Humanitarian Day is a day to remember aid workers who have lost their lives helping people affected by disasters and celebrate the spirit that inspires humanitarian work around the world.

Why we love it: by getting permission to post more than once on each person’s account the campaign managed to amplify its social activity.
