I'd like to have my 'mugshot' in Google's SERPs but I couldn't care less about Google+. I don't really want to link my website to Google+ either. Can I use CSS display:none; on the link leading to my profile and still have authorship, which looks like

<a href='https://plus.google.com/111823012258578917399?rel=author' rel='nofollow'>Google</a>?

Will the nofollow attribute here spoil things? I don't want to lose 'link juice' on Google+ if I don't have to.

Now Google should crawl only the HTML but I'm sure they'll figure out the link is not visible (perhaps it's technically even cloaking.

Does anybody have experience with this situation? And do I really have to become (reasonably) active on Google+ in order for authorship to show? This answer suggests I do but I didn't read anything on that in Google's guidelines.
