As an IT professional, you need to stay on top of trends, new technologies and new products and services, but you probably don't have time to read every interesting article you find online. Instapaper allows you to save Web pages for reading offline later.
However, it doesn't just save them. It optimizes them for readability on the iPhone and iPad touch screen. It also allows you to browse and save posts on Facebook, Twitter or Tumblr. Additionally, it is supported by and can be used with more than 150 other iPhone and iPad apps--and it even supports email, which can also be sent to it for later viewing.
