How the GetGlue add-ons traditionally work is that when you are on a page like IMDB or Amazon.com, you can get certain information about a product or article within a little JavaScript GetGlue pop-up. This pop-up lets you see which friends have liked an album, read reviews, watched videos, etc.
It's a really nice feature and it adds a lot to the Glue experience, but the problem has been that you can only see these tips when visiting Glue-supported sites. Now, if you install the GetGlue add-on for Firefox or Chrome, links to IMDB, Last.fm, Wikipedia, Amazon and dozens of others will feature a little "Glue Tip" icon. Hover over that icon and you can get access to all of the Glue-sharing functions.
This means that if your favorite blog or your Facebook feed links to IMDB, you can mouse over to see not only the IMDB info on the actor or film, but you can view reviews, see what your Glue friends think, rate the item yourself or save it to your favorites. You can also tweet or share the link via Facebook, and if it's a purchasable item, buy it from one of many different online retailers.
The beauty of something like this is that it is unobtrusive -- you only get the info if you hover over the Glue Tip -- plus it brings added context and information to what you are reading, or, more importantly, what you are searching for online.
We like that when it comes to music albums, for instance, you can choose to buy a disc from iTunes or BestBuy -- even if a link originates at Amazon.com.
