Last night while I was Googling whiskey in russia, came across this great YouTube show of how to prepare a pub in Russia. The preparations that are made are typical of the Moskovsky Bar in the Four Seasons Hotel in Moscow. The detail had me completely in awe. Never seen anything like that before. If I win the lottery one day that's going to be definitely a place on my list to visit.. Probably one of the best YouTube shows I've seen in a while.
PS since you're drunk do you want to design a plugin? I think it's a requirement for creating this specific plugin.
Basically I see this dream plugin as an option just below the IP in the posts that is visible to staff. The link will say "Show duplicate content" and only needs to work on demand so as to save resources. If one clicks on the link, there will be some magic happening where the content of that post will be compared with the content of all of the other posts in the same thread. It will then end up with something like "No duplicate content found" or "Duplicate content found with a link to the post that has been duplicated".
