I am currently writing my master thesis and I am also running a popular blog about my research area. Some people asked me about certain topics and if I could write about them on my blog to make them more understandable to newcomers in our field.
Now it is tempting for me to just copy parts of my yet uncompleted thesis and mash together into blog posts. This will help me to save time writing them (I usually do not have the time) and it will benefit others. However, I worry that people see that as self-plagiarism. In particular people on the thesis committee might say I copied parts of the thesis from the internet.
What would be the right way to save me from trouble here. Shall I cite my unpublished thesis, or should my thesis cite my blog posts? Should the blog posts have clear indications that I copied verbatim from my unpublished thesis? Will I get into trouble if people see that in my thesis I copied verbatim from my blog posts (if I cite my blog posts rather than the other way around).
