I’ve mentioned the headup publisher widget before. This nifty add-in identifies entities (places, people, companies, books, etc) mentioned in a site it’s installed on, marks them up with a dotted underline, and when you mouse over them a small pop-up comes up with information, news, photos and videos about that place/person/whatever.

That was then. Now Semantinet, the start-up in Herzliya where I work one day each week, has packaged the capability as a WordPress plugin, which means that a blogger can add the capability to any WordPress blog in a mere minute or two. If you have a WordPress blog, you can download the plugin here.

What’s more, the product had evolved, and it now includes a tab called “friends” in addition to the ones for photos, videos, and the rest. This tab – once you connect it to your Facebook account – shows you how the entity being viewed is connected to the people you know, like which of your friends live in the place or work at the company.

Pretty powerful capability – and easier than ever to include. Which is what I just did – mouse over the marked up words anywhere on this blog and see it in action!
