I totally agree with Reed on this and vote to move academic writing to Academia.SE.
A writer who writes a novel is a writer, and nothing else, at least not in relation to his novel writing. All he does in relation to writing his novel is writing his novel.
An academic author on the other hand is first and foremost a researcher and scholar, and his writing is only a necessity like taking care of administrative duties, finding funding, hiring a new secretary, etc. All these activities don't make the scholar a financial expert or a HR manager, and neither does publishing his research make him a writer. In fact, many academic authors (note the word "author" here, instead of writer) deeply dislike writing, and a majority are extremely bad at it. And neither their dislike for writing nor the low quality of their writing really matter, because those texts are not read because they are well-written (althought that does help), nor are they written out of joy in writing. Their sole purpose is the transportation of information, and their stereotypical, monotone and uncreative structure – which is a must! – reflects that.
So, academic writing is writing, surely, but it is fundamentally different from journalistic and fiction writing and certainly more closely related to other questions about academic practises than to writing a poem.
I don't mind that academic writing is on topic here, but I find it doesn't really fit.
