Well, it's fairly dull. It seems to commit most of the 'sins' that blog-readers speak of. Nothing of note, or comedy/tragedy/mystery, or with a 'theme', streak or thread. All of the detail re scans/diet/procedure is well-known. The 'excitement' is personal, and I think that's mostly where it falls down - you appear to have written it as a 'diary' (or journal, as you say) not a blog. But overall, there doesn't seem to be a target audience, you haven't fashioned it with that in mind, I think.
