I really like it that my account is shared on every localised lastfm. In fact, lastfm is just on big base with localised regions for content, that's really great.
I think it would be nice to be able to localise the text in the "About You" field of the profile in one (like today) or several languages.
Wouldn't it be ?
EDIT: Don't get me wrong, this would be a gadget, not something really important.
