If you’re on so many social networks you’re losing track,  or you don’t even know where half your early network memberships are, you might want to check out Retaggr.

Similar to Google Profiles, Zooity and MyBlogLog, Retaggr condenses all your online information into one handy place. Yet once you start messing around with Retaggr, you see it’s a lot more than a simple online contact hub.

As well as giving you the option to save all your profiles in one place, Retaggr acts as the ultimate social business card. Your contact details, work address, website, blog, street map and more are instantly available.

It also shows what blogs you’re reading, what you’re discussing around the web, multimedia uploads, your latest blog feed and online resume service just to name a few. You can then use that information on a handy business card that you can place on your blog or website. Check the Retaggr card under my short bio to the right, or the main card on my About page to see how it looks.

While Google Profiles shares similar ideas, the interactivity of Retaggr makes it a completely different beast.

You can email someone directly from their business card; join in an IM chat; listen to their music library on the likes of Blip.fm and much, much more.

As you can probably tell, I’m impressed. Even though Retaggr has been out a little while now, they continue to add to and improve their features. If you’re serious about your online presence, I can’t recommend Retaggr enough – it really is that cool.

Check out Retaggr for yourself or have a look at my extended profile and let me know what you think – useful? Will you use it or give it a miss?
