Most likely you have at least one friend who can program, and they can take advantage of source code. To a programmer, software without source code is like a car with its hood welded shut. While flaky software is somewhat acceptible on a home computer, it's strange that people will use it when their professional name is on the line. These publically-visible crashes should give programmers and advertisers out there some food for thought. Well, there's no good benefit nowodays, and on a computer, there's no particular reason to stick with it.
Many Web pages are junk.
To help cope with messy web pages, you might try filters like Muffin . To avoid putting out junky web pages of your own, try validatiors such as validator.w3.org . JavaScript is terrible. I usually use browsers that support JavaScript, yet nevertheless I leave it disabled. Authors, if your site requires JavaScript, I will leave unless I desparetely need the content.
