Public outreach is an important part of being a researcher, in my opinion, and blogging is the method of choice for many researchers. Is it okay to share recent research progress, explain publicly what you are doing, what kind of experiments/simulations you are running, why you chose these kinds of simulations, and the main conclusions you could draw from the simulations, and what you think comes next? I am not sure if research group leaders are keen on such being made "publicly available" before a paper is published. Of course, some might read your idea and realize something huge, do it themselves and take credit, and claim they came up with it independently.
I hope to get a PhD in computational chemistry in the next few years, and I would very much like to share ideas, share my thoughts, and explain concepts as an attempt at public outreach. This would, naturally, lead to sharing of some group-specific ideas and progress. Is such behavior generally supported by research group managers (or the university in general)? How would journals respond to publishing papers where some progress figures and ideas have been "published" on personal blogs?
