It is not very clear in the publication guidelines of journals or conferences whether one can post some preliminary data or results online (blog, twitter, facebook, etc.), gather feedback, and then edit and publish such results in a journal or conference publication (but in other fields it has happened with some embarassement).
Can a researcher post a blog-entry, or use twitter, sharing data and results with a journal or conference paper? Would it be considered self-plagiarism?
I would argue that the communications on a blog would need to be cleaned up significantly to be published, even supposing it was indeed new research suitable for academic publication. You would need to get some kind of idea of the nature of your comment providers. Are these academics? Trolls from some high school? Residents of a home for persons with severe mental illness?
This is most especially true for any area of study that is in any way controversial or in contact with politics. The chance that some group of 3 or 4 trolls in some high school's computer lab have made a "project" of you is worrisome.
Recently an on-line magazine "came out" and announced they were disbanding. The magazine had been publishing semi-scholarly articles about third wave feminism, intersection analysis, and such. For almost 3 years. The problem was, they were too good. People believed they were real, when they were in fact nothing more than deliberate satire. University profs were asking them to come and give talks to their grad students. They fell afoul of Poe's law.
In addition, in some areas, you need to keep in mind the Sokal affair.
It would be mighty embarrassing to be the "tip of the spear" of another such incident.
