Last week I was in charge of running the #scicomm twitter account @labioaulabo. Every week, a new researcher involved in the field of biology describes his/her everyday life, how he/she got there and engages with the community to explain his/her work. It was a very rewarding experience, where I got to learn how to better communicate my work, especially using twitter. It's all in French, but there are similar accounts like this in English. If you can, try it, and follow them, it's worth it.
