I have completed my Masters, and will soon be beginning a PhD in my field of research. Recently I had an idea that I could start a blog that would explain some papers or concepts I found interesting in a more pedagogical way as compared to peer-reviewed papers or literature reviews. I do understand that a blog in no way can be a replacement for actual peer-reviewed research. However, the reason I would like to blog is so that I feel motivated to learn new topics that I find interesting. In the past, I have found that I learn best when I can 'apply' the knowledge I have learned, and a blog in my mind could be considered an 'application'.
The worry I have is that I do not know how academics perceive such informal scientific endeavors. Is the level of informality in blogs considered too unscientific and frowned upon? Or could this ruin my chances of employment in academia after a PhD in case a supervisor considered this a 'waste of time'? (or although I imagine it to be improbable, can such a blog cast a favorable impression on a supervisor?) Then there is also the issue of whether a blog is worth maintaining since it would take up significant portions of time that could have been spent on other things.
What are your opinions (and your understanding of general academic opinion) on such blogs?
