I have seen various posts that describe wish-list items related to reviews but not much specific to the current question: How often, if at all, do you go back to make updates or edits to a review that you made in the past? I really like trying new beers, but on those occasions when I do have a beer that I previously reviewed I will often go back and see if my current impression matches my original impression. If it does not, I will update the commentary and/or the score(s). Occasionally I will note how one perceived aspect no longer matches my original impression. If it is a significant change I will add the date of the revision to the new commentary and reference to original date of the review. Just curious how many others do this.
