Just for fun, but who knows... some may good/useful.
Two from me:
· BUSINESS CARDS, such as mine...

· SELF-MADE WIKIPEDIA PAGES. Many musicians/bands etc. have them. You can just register on Wikipedia and build one. Give links to your sites/music... I can't see what would be stopping us?
Any others??
