Recently, I read a paragraph from the book, HTML and XHTML by Dick Oliver
Feb. 2001, which resonates with my belief that we at MATC should consider adopting, promoting, &/or encouraging the use of .HTM as our default document type. Here's an excerpt...

The near-universal compatibility of HTML and XML provides a big incentive to format any important document as a web page --even if you have no immediate plans for putting it on the WWW. You can create a single page that can be printed on paper, sent as an email message, displayed during a board meeting presentation, and posted for reference on the company intranet. You also can take the traditional route and format the page separately for each of these applications --and edit each file with a different software  program when the information needs to be updated. Now that most business software supports the HTML standards, many organizations are trying to get employees to consistently use HTML for all important documents.

I could list a lot of reasons in favor of the format, but I think you already know what they are. I think we should teach it, model it, and promote it. We can call it web-page format instead of HTML so it sounds friendlier. 

End of soapbox... What do you think? Yeah, I know... it's old news, and it will never happen. I suppose some would argue that we should just continue to use Word 2000, XP etc., because they can create web pages. I might even agree with this if Word was used to create web pages from the start, and not in the default .DOC format. Unfortunately, this is what 99% of staff will do because it's the default format.
