Whenever i can Iprefer not directly to write on facebook. Instead I write on my wiki page and then put the link to that on facebook.

Try going back and finding something your wrote on facebook even a few weeks ago. For that matter, do a screen refresh on your browser and see if you can get back to what you were previously reading. Often you cant.

Facebook is not a normal webpage. Normal on web pages when you hyper link to another page, and then by clicking the back button to return to the page you came from you, will go back to exactly where do came from. But not when you using facebook.

Facebook users an algorithm to return you to the page, it wants to return you to. So effectively Facebook are controlling you.

Facebook want you to read the pages they want you to read. They say the algorithms based on your viewing habits. But when they're controlling your viewing habits how can that be the case.
