Amen. Tags are fun, especially when we try to be creative in selecting them. Unfortunately, it makes it rather hard to find content. Forcing people to select only one tag for a post would usually result in a) people not tagging a post at all or b) people selecting a very general tag as to be worthless or c) people using a 'creative' tag resulting in a tag "ghetto" ( forgot who first used that word)

I wish citing a paper is as easy as using apt in Ubuntu or importing a module in Python. We need an open access journal. Open source too. Where the papers and their associated datasets are hosted as well. That way we can just fork them if we think of something more interesting to do with the original research.
