Apologies if a post on this topic already exists, I wasn't able to find it via the search box.
My question is about the ethics and basic rule of thumb about changing past entries. I've been working on the Bloggiesta this weekend, updating tags and categories for nearly all of my posts since day 1. Reading through my blog, I've come across a number of entries that I want to competely rewrite. Most are of book reviews.
What I wrote about the books reflected my emotions about the book/movie, etc at the time. But I have since grown, and changed my mind on a few titles. Is it OK to go back and change previous posts, or should I just leave them as is?
Thanks for you advice!
