"Blue Monday" fell on 15 January, apparently one of the most difficult days of the year. Mind and Samaritans have rightly warned of the risk of trivialising the complex and sensitive issues of mental health, but what I love and admire is their cheering and empowering communications response. Samaritans, for example, brewed a nice cup of tea and turned Blue Monday into "Brew Monday", encouraging everyone to get together and, in doing so, raise awareness and funds for its work.
Charities have pioneered the creation of citizen science tools, with wondrous results - from Friends of the Earth's Great British Bee Count, mapping the health of UK pollinators, to Cancer Research UK's Genes in Space project, working with thousands of people to analyse kilometres of breast cancer DNA. This year the British Science Association and The Plastic Tide will help people use drone footage to track and tag millions of images and help clear our oceans of litter and plastic - an idea to gladden the hearts of David Attenborough and millions of Blue Planet fans.
As with Brew Monday, you can't beat a bit of direct contact, and I'm already looking forward to the Jo Cox Foundation's second Great Get Together this summer, when communities across the nation will celebrate what unites more than divides them.
I am optimistic and excited about what 2018 will bring and I am lucky to be working with brave, purpose-driven charities that are grasping the opportunities of the rapidly changing communications landscape with both hands - like a warming cup of your favourite brew.
