Social media have become a new tool to get publicity. Some journals run their own social media divisions. Some researcher are very keen to be represented in social media by their own blogs or tweets. However, there are different options around and the decision for a specific type of social media requires some thinking.
The decision which tool might be appropriate to communicate about science with which audience is really difficult and any effort is limited by available resources. A recently published paper in PloS Biology summarizes pros and cons of different options. Maybe this an entry point for you to go this way – maybe this is the stopping point to end with rumination about the question “Should I invest time in social media?” by answering this question with NO.
Here is the paper.Quite short. Well written.
Enjoy reading, Jürgen
