LET US TAG PLACES, let us make our own tagging catagories so that we can track the frequency of various different things. Let us see everything that we've ever tagged---why limit things the way you are now? it seems to upset the whole idea of dreamboard.
Also the tag system is buggy. Most of the time it won't let me tag new people. But let me say that it's really, very odd that you can ONLY tag people.
