From the past discussion:<p><a href="http://wirfs-brock.com/allen/posts/914" rel="nofollow">http://wirfs-brock.com/allen/posts/914</a> - a direct response, well worth the read as it provides more context and a different perspective.<p>From my recent reading list:<p><i>Evolution of Smalltalk: From Smalltalk-72 through Squeak</i> by Dan Ingalls: <a href="http://worrydream.com/refs/Ingalls%20-%20The%20Evolution%20of%20Smalltalk.pdf" rel="nofollow">http://worrydream.com/refs/Ingalls%20-%20The%20Evolution%20o...</a> [pdf]. It's 101 pages but also worth reading, if for nothing else that what I found to be a really interesting story of how Smalltalk-80 was essentially bootstrapped from the similaryl named but nowhere as capable Smalltalk-72<p><i>The Early History of Smalltalk</i> by Alan Kay: <a href="http://worrydream.com/EarlyHistoryOfSmalltalk/" rel="nofollow">http://worrydream.com/EarlyHistoryOfSmalltalk/</a><p>Kay and Ingalls do a good job discussing the actual history of Smalltalk but with their own focus being on what it <i>enabled</i>, with very little interest in the actual commercial side of things. Wirfs-Brock's post gives more information about the context of Smalltalk in the commercial and enterprise setting.
