I actually don't like untagged maps. I need a little something-something on a map to get my mind going. I prefer to see maps that are labeled with vague tags like "church," "priory," "Guildhouse," or "city jail." This way, I get a general feel for how the person who designed the map conceived his/her map should flow. I very much appreciate the ability to edit the individual labels, however. Sort of gives me the best of both worlds...I can nick ideas and get some ideas going based off of someone else's (hard) work, then morph things to suite my own taste.
Completely untagged maps are actually pretty hard for me to work with. Too bland.
