I've been attempting to organize how Bitovi approaches web application development. I'd like to draw a line from what users and businesses value (quality) to the techniques and tools we use to build web applications. I've organized my thoughts into a mental map:

In this article I'll explain a simple, fast way to perform user testing, even with no budget or time. A lot of people don't immediately see the value in doing user experience testing, partly because it has the perception of being an expensive hassle or just a waste of time.

Similar to jQuery with DOM elements, $.Range provides a simpler API and cross browser methods to create, move, and compare text ranges. If you need to create a custom text editor, text highlighter, or other functionality that understands text, $.Range can be a huge help. For example:
