I think Geni could use a own library (kind of a special photo album) for coats of arms. Or a collaboration with an existing provider like http://www.genealogie.com/v2/services-blasons/default.asp or Wikipedia:
- coats of arms are now mostly added without permission
- the quality is often poor (often gif with that ugly black background and withe dots around it)
- the coats of arms of historical profiles are now stored in the photo albums of Geni users
- coats of arms are very relevant for historical profiles
What do you think?
