Is it a very important feature and should you cater to the lowest denominator and build using progressive enhancement, or can you use graceful degradation and/or supply a lower-level alternative, or is it just a gimmick and is it ok to ignore part of your audience?

In internet-terms that's a lifetime; back in those days Firefox didn't exist yet (Mozilla Phoenix was on version 0.8 or something and IE6 was the dominant browser), we didn't have HTML5 or javascript libraries and web standards was just a grass roots movement. It was hard to make dynamic cross-browser things back then, yet I managed to create something that still works in browsers today.

I pointed out in the comments that there might be more in play than just the fact that some browsers don't follow the specifications (notably mobile browsers) to the letter with regards to DOM-tree building.

If finding the right tool takes too much time there is only one other option: create your own tool, which is exactly what we did. Even better: we are releasing this tool to the public so you can use it too!

I also used the Array generic Array.filter there and left those with a promise to explain how these techniques can be implemented crossbrowser.

I also took a shot at it back in 2005 and back then Opera had some performance problems with getElementsByTagName, IE's implementation of nodeList.item() proved to be a major hog and Firefox' XPath implementation was far from perfect. Eventually I came up with a hybrid solution that combined the fastest approaches for each tested browser (with IE being declared the winner on performance).

I noticed this recently when I was benchmarking my own getElementsByClassName function and comparing it to the established javascript libraries that also support this functionality.

Who doesn't experiency the ease of webdevelopment using extensions such as Chris Pederick's webdeveloper toolbar or Firebug in Firefox on a daily basis? Ofcourse there is no job without some downside which in the case of webdevelopment is the necessary support for not-so-developer-friendly browsers such as Internet Explorer. Sure enough there is a developer add-on for IE, but in the apartment where we need the extra help the most it is still lacking an important feature: the ability to edit style-rules in real-time.

Although these articles were written with the best intentions they should in my opinion have a big red warning-label saying "beware of premature optimization and browser-specific implementations".
