Tagging is good for categorisation (which reddit has already implemented using "subreddits"), but tends to result in a lot of noise when users can apply arbitrary tags[1]. Additionally it's a lot of extra work on the part of the user to specify meaningful tags - this is especially undesirable considering that reddit's aim is reducing the amount of work required to submit pages. What would be more useful is an subreddit discovery feature allowing users to subscribe to subreddits which interest them (this would also reduce a lot of the cross-posting because similar subreddits like /r/python and /r/programming would share a large segment of their audience).
