Any difference from the existing one on this page?
I guess the only real difference is mine is available through the Chrome Web Store and has the full extension source hosted.
EDIT: Checked with a few people, no one remembers seeing the extension link earlier today. Can anyone confirm when they first saw it? (I saw the post around 10 this morning and decided to write the extension. Just want to confirm my efforts weren't totally in vein)
The extension only adds more social links the "Related People and Pages" sidebar. Even then, it only adds links, it doesn't remove the Google+ pages. Your regular search results are not modified at all. Try searching for "movies" to get a better feel for what it actually does.

Neither of them show up after I install your chrome extension because the "Show Personal Results" is enabled by default. Your extension does show those G+ profile pages ONLY IF I switch to "Hide Personal Results". This is a problem with the original bookmarklet as well.

The extension was not available when I started working on my own. Phew!
