A few days ago, Kobo turned 1 year old. To celebrate the anniversary, the company enhanced its iPad and iPhone/iPod Touch apps, adding Instapaper integration and new social-media features that allow you to share what you're reading with others.
All in all, the Kobo iOS apps look more jazzed up and we expect all the big e-reader players to continue building out the social-media functionality in their apps (Amazon and Barnes & Noble also feature social-media hooks in both their devices and apps). The Instapaper integration is interesting because it allows you save Web clippings as you surf the Web and store them in your Kobo library for later viewing. You can also sync those clippings across multiple devices.
For more info on the enhancements, read Kobo's full post detailing them. Also, let us know what you think about the whole concept of making reading more social and, if you've used the Kobo app, how it compares with Amazon's Kindle and Barnes & Noble's Nook apps.
