Was read through this nostalgic [webmasterworld.com] and it made think of my days of 300 baud modems, RLL controllers, and the WWIV (World War IV) bulleting board systems. I think you can attribute specific "features" on those old BBS software to modern day browsers and forum scripts. For example, when you were reading a discussion and you wanted to go to the next page of text, you would press the space bar. With Internet Explorer, you go to the next part of the web page by pressing space bar.
I think a lot of cool features never translated to the web, although they could have.
Oh, the moderat "flat" display of threads such as here, is a direct take off on bbs systems such as CNET for the Commodores and Apples. The success of WebmasterWorld owes a great deal to those early days of bbs'ing.
Any thing you can specfically think of that could translate?
