== WP:BRD == 

 I returned this sentence to its original condition: "With the introduction of proportional fonts in computers, the convention for sentences became obsolete." 

 An edit was made to modify it earlier. I reverted it and initiatied discussion on the talk page. IAW WP:BRD, discussion now follows until a consensus is achieved. Continued back and forth will just lead to accusations of edit warring. We're all reasonable editors here I am sure, so there's no need for that.  

 Finally, I don't want to imply that I am not willing to make modifications to the article. I simply want to discuss it IAW policies. Thanks.
