Below is what I get added to a post I'm writing when I right-click on your node's link, click "Copy Link Location", click "Add Link" in G+, then right-click and click "Paste":

Free publicity Free publicity. by Steve_BZ (Friar). Log in; Create a new user; The Monastery Gates; Super Search; Seekers of Perl Wisdom; Meditations; PerlMonks Discussion; Obfuscation; Reviews; Cool Uses For Perl; ...

Then, since the description provided has more to do with site navigation than the node, I can click "remove description" and have just the link. That might be worth looking into, giving the pertinent information to services when it's requested through that sort of interface.

Is it a little more work than the +1 button? Sure, but I'm sure I could have a +1 in my free nodelet as everyone says about the other services. Does it keep my browsing habits fairly private other than the fact that I do read Perlmonks? Yes. Yes, it does. And my homenode is already linked as part of my profile anyway.

I have to wonder if what PerlMonks really needs is people clicking +1 to outside sites as often as they upvote a node. Maybe actually thinking about whether you should take three seconds to switch tabs and all to promote this or that particular node is actually worthwhile. Then again, I remember walking across the room to choose whether I wanted to keep watching this TV channel or switch to the other one.
