This question is similar to Overcoming Fear of Rejection, but not the same.
My experience in academia was teaching Computer Science for four years at a mostly liberal arts college, and that was 30 years ago. I frankly found the world of work to provide more challenging intellectual stimulation, at least in the sort of practical issues I cared most about.
There are highly technical issues in software development that I and other practitioners have discovered that are quite orthogonal (to say the least) to the trend of publishing in those areas. So when I try to publish it is hard to build much of a bibliography. When I submit (through an online submittal process) I tend to get responses that vary in quality, but are generally negative.
I am tempted to revise, in such a way as to address the concerns raised by the better quality reviews. I could buttress the claims with stronger mathematical arguments, but it's hard to tell if this would make the paper more or less approachable.
Then there's the question whether I should resubmit to the same journal. There don't really seem to be any others at the same level of relevance to practitioners.
Sorry if this is a noobie question.
