If you’re writing a serious application, on the web or otherwise, you’ve got to have good logging. In the context of application development, reading logs is my personal favorite method for tracking bugs and rooting them out. A service like Loggly is perfect for programmers like me. It provides an easy to use web interface with searching capabilities that allows you to see what your application is logging at any time that you’d like to check in. Debugging with Loggly is nice, but it’s just the tip of the iceberg, thanks in part to its Loggly API.
It is not uncommon for e-shoppers to create a cart on a website without the intention of making an immediate purchase. The motives behind abandoning a cart can vary; what matters is how companies take advantage of the information that can be gained with each cart that is left behind. Rejoiner is a company that helps online retailers capture, analyze and recover abandoned shopping carts. The company accomplishes this with their Rejoiner API.
