[5]The article is a bit dated (statistics through July 1994) but it is a decent overview of how the Web developed and where it is headed.

[6]Yes, there are alternatives, yes we could argue over which is best, but that would be silly. Netscape sets the standards all the others are trying to keep up with or surpass.

[7]Ditto above. WYSIWYG's (What You See Is What You Get, or Whizzywigs) offer some attractions, but BBedit is the workhorse perferred by the pros and students who use it understand html much better than students who use a WYSIWIG. You can download a copy here

[8]A few basic html sources are: for a "Quick Reference Guide" go here.

For a comprehensive html guide go here

For a well designed instructional guide go here.

For a well oganized comprehensive guide to HTML resources go to the pros.

For a disorganized always changing hodgepodge of html resources, go to my personal bookmarks and find the HTML section.
