Blood, Rebecca. “How Blogging Software Reshapes the Online Community.” Communications of the ACM 47.12 (Dec. 2004): 53-55.
Blood folllows the history of blogging and notices how blogging software adapts to bloggers needs and makes blogging easier. She notes that as a practice becomes more popular, blogging software tends to develop tools to make that practice easier to do (e.g., permalinks, trackbacks).
This might be useful to refer to on permalinks and trackbacks, if I use those in my paper.
