When reading books/articles, sometimes I find it very annoying when the writer focused more on using difficult & bombastic words, rather than putting more effort to make his/her work more understandable & accessible to the readers. I think, it is very important for essay to have a clear, fluid, and smooth transition, as when there is no clear link between the ideas, people tend to be lost by the end of the paragraph. But well, perhaps my language skill is just not up to the standard yet, in understanding those texts.
Simplicity, and elegance. I need to learn how to write even better. :)
