Fram: I fully agree with your last sentence.
Maryana: For me, the big reason why people would post quicker instead of first reading, is because of the lack of overview, which encompasses
- no ToC for topic-level browsing,
- too much scrolling required to read within topics content,
- only one indent level.
At least that's my experience. I find it painful to browse all those comments almost one by one due to the lack of structure, and I hate scrolling while seeing so much white space around (not just vertically, by the way: most of the unused space is located on the right side. Actually, fixed width is exasperating: please allow us to let window content adapt to the window size so that we can choose our own preferred width by simply resizing one's window... which is possibly done already for reading pages in the main namespaces such as Wikipedia articles anyway).
