Most content creation tools (think WordPress, MT, Blogger) relegate content creation to a secondary page. Adam Mathes argues that this is bass-ackwards, complete with examples:
Twitter gets it right. This is why anyone - even confused celebrities who barely comprehend technology - can actually use this product. You show up, there’s a box at the top, you type in it, and it shows up below with other people’s stuff you can read.
If content creation is the primary action, it should be presented that way.
