There's a big difference in blogs that present articles rather than news stories which just keep coming, are interesting then lose interest daily. When posting articles the standard way there is a strict disadvantage to writer and readers when new ideas or information surface that will substantially improve on the compositions.
With a workable procedure posting improved fresh updates can be very beneficial.

• Enter new ideas and add fresh material as they come to mind.
• Change the title, rearrange and edit the total article.
• Upload as a new post when suitable.
• Delete the old post, leave intact or edit to a few lines and hyperlink to the new page.
• Delist from the sidebar. A manually produced archive list(s) would be useful here.

thanks for sharing your experience.

Those were great tips, since writers do experience hitting the dead end sometimes. And I also like to add, that reading others article is also a great way to get inspired, motivated and get your brain working. Though I don't advise people to copy from others work. Its always best that you create your own.
