From: "Richard XXXXXXXXXXX" To: Subject: Re: http://www.webword.com/reports/period.html I was pointed to your site by a friend and wanted to point out some issues that I don't see addressed. If ASCII had separate characters for period and decimal point, this wouldn't be an issue - there'd arguably be more spacing after a period and less after a decimal point. Have you had any luck in the intervening time following up on Keith Rayner's study? Even without the study, it might be simple enough to ask whether additional spacing was found to HELP or HINDER readability. Regarding ""rivers" of blank spots" - this only occurs in "fully justified" type. This type of spacing is rarely encountered on web pages. Travis Wall doesn't "get it" - "designers" should be making PDFs if the fonts and layout are important. HTML was originally about structure, not layout, although presentation-specific tags (and stylesheets) have been introduced through the years. On many (most?) web pages, the "designers" don't even specify a font, so the pages are still readable on a PalmPilot or cell phone. PDF is all about presentation. It would be really handy to have four GIFs or PNGs demonstrating monospaced and proportionally spaced with both one space and two spaces after the period. Indeed, the "next level" would be to have four copies of your web page - monospaced one space, monospaced two space, proportional one space, proportional two space. Then people could empirically decide what looks good. Oh, and what about question marks and exclamation marks? Is the rule different for them? :) And I won't even get into colons - controversial in monospacing! :) And then there's e-mail - both monospaced and proportional font mail readers are well-represented in popularity. And Usenet News, where monospaced is arguably more entrenched than proportional. Thanks for the feedback opportunity. I'm hopeful that, of the above issues, you'll find at least one item "new".
