If you cannot be so careful who your neighbours are as self-selected upper-middle class people can be, the logical solution is absolutely to avoid friendliness or casual offers of help. (p65)
Jacobs brings class into the scene here. I’m not sure that this fully translates into the online educational world, but there might be similar class distinctions between levels of activity – something like Networked class systems, just to play along with the term “class”. Those who are pedal-to-the-medal online tend to experience a wider variety ‘interactions’ than those who moderate their online use.
The high users will (generally) have the benefit of bigger networks & more opportunities for learning, and more opportunities to receive help…not to mention they may gain a better sense of which ‘interaction’ suits situation.
Those with smaller networks may have to be content with their own pace and balances, even though larger networks will naturally attract more opportunities (friendliness and offers for help). Hopefully design is conscious of these different ‘classes’…especially when designers and instructors are of the ‘higher class’.
