*Applaude*. I really enjoyed reading this, because that is exactly the
spirit I like to have in OSM. People who just use tags. :)

My hope is, that more people just use the tagging system at what it is:
A big storage of key/value pairs to do creative stuff with ;-).

And if someone likes your "ibm" (btw: what does it mean? ;) tag, then he
can rename or copy the tag to something like "important=yes" ;-)


(And if anyone say anything like "performance" or "privacy", then we
will probably need tag-separation by different servers to solve this.
IMHO what we don't need is rigid structures.)

Just my two cents, Imi
