Introductory Greek grammars have been available on the web for some time now, but several are simply web versions of what is available in print, or are the notes of a Greek teacher presenting his or her favorite sequence and wording of what is already available in print.
What should be different about a web based grammar? What would you like to see in a web based grammar that you do not already find in a printed textbook?
I ask these questions for a concrete reason. I would like to add an introductory Greek course to Greek-Language.com. I want to make it a truly native web experience, containing interactive exercises, reading passages, etc. What features would you like to see it include?
