time stamping

I read this article where it said time stamping was really essential to the nature and the identity of a blog as a textual thing. Because it makes it different from a webpage because things come up in reverse chronological order and it is a changing thing because of the archives and stuff. But on blogger, you can totally go back and edit/ delete your posts, as well as change the time stamp on things. It makes it so unless someone had been reading a blog along the whole time, you could totally write a whole blog in like, three months (or I dunno, however long it takes to write a book) and post things all at once, and the blog would just APPEAR and not be immediate. Or you could lie and write two posts in a day but have them be timestamped on different days... or you could accidentally refer to something a bunch of times without saying what it was, and then go back and timestamp something before you started reffering to it and say what it was so all the other posts makes sense.

I dunno. I kind of like it (and have used it for this blog when I have two things to post that are totally different, like writing one and saving it for a day to post it) but I think its really weird that:
a. I feel like I am manipulating time and
b. that people (pretty universally) think of a timestamp as a defining characteristic of the blog and you can basically manipulate it all you want.
c. that we have the ability to manipulate it in the first place. why is that even a feature?

Although it seems like you can do some pretty interesting stuff with that. Like I could go back and fill in the blanks of high-school internet me as (almost) post-college me via my internet blog and no one would really know that I'd done anything, because of the timestamp. I could have written that whole blog this semester too, and who would know? I guess there are some people who read it while I was writing it (maybe?) but still... That's kind of crazy.
