SparkTab is kind of like QuickSilver for your browser. Instead of setting your new tab page to, say, Google, you would add SparkTab. From the text entry bar, you can perform searches, send texts, and even post to Facebook and Twitter. Think of it as a quicker way to do lots of stuff online without having to enter a URL or click on search results.
