Even more so, essays, like the serial novels, are antiquated formats from the time of letter-writing and paper publishing.
At least the Victorian novels gave way to their readership's desires and moved to a more concise format. The essays, annoyingly, remain overly wordy as the academic standards retain their obsoleteness in demanding a set word counts.
Already, the short novels are becoming dominant in the on-line publishing sites. With any lack, the current tide against the printed humanist\scientific publishing houses will bare fruit soon and in a decade or two we will be reading the thesis, facts and analysis rather then the dribble we've become accustomed to.
Present me your thesis in a sentence and a few bullet points: List the facts; Lay the arguments; Tie it all up in a paragraph. I don't want long prosaic discussions or fine poetics.
Further, I think it's important for a scientist or philosopher to fully and completely elucidate his or her point so that any debate over the subject is based on a complete understanding.
Would you prefer that a study not outline its methodology and full application of said methodology, and instead simplify by just giving you results? How would you reproduce it? Would you just blindly start trusting everything printed?
