A technology with low barrier to entry can be a double-edged sword.
A technology that people can speedily and easily use will probably be adopted very quickly. However, there is likely to be a correspondingly low level of quality control.
HTML’s Explosive Growth
HTML’s ease of use is one of the reasons behind the explosive growth of the Web.
Anyone can learn the basics of HTML in a short space of time and create a web page very quickly.
It’s even possible to use WYSIWYG editors to make web pages without ever seeing a line of markup.
The downside to this is that most pages on the Web are badly formed and don’t validate.
Browser vendors have to accept this state of affairs by making their software very forgiving and unfussy.
Much of the code in browser software is dedicated to handling ambiguous use of HTML and trying to second-guess how authors want their web pages to be rendered.
HTML’s low barrier to entry has been a mixed blessing for the Web.
