OK so here is the deal. The Show my Email address option does not apply to instant message coordinates. So if you have an email address in your IM Username field Blogger will display that in your profile.
I think this is a bit silly because I clearly have not shared my email address. Further, there is no setting to share / not to share your IM address. Be weary not to include your IM Username.
I guess an email address isn't an email address as far as Google / Blogger are concerned. I'd just as soon not share any email addresses when I specify not to - but I guess this is a loophole.
