It's not explicit in the question but, https://softwareengineering.stackexchange.com/questions/128344/would-smalltalk-be-a-good-introduction-to-programming, to me is just another form of "Which language should I learn next?" The OP has found an online resource and is, I think, really asking "is this a good introduction to programming for me".
I flagged it as "off topic", which was the closest match to what I was trying to express.
