I would add that one should be careful not to do as Microsoft does in their “help” documentation and tell the user “You can…” without telling the user “Here’s how you can…”. One should be quite explicit and literal, e.g. “Under the ‘Statistics’ menu select ‘Basic Statistics’ and from the resulting menu select ‘ANOVA’ …” instead of saying “You can perform analysis of variance on a dataset…”.

Don’t tell me what I CAN do. The sales literature should have told me that. I have already bought the damned thing. Tell me HOW to make it WORK.

Good article, and the podcasts are extremely helpful. Keep up the good work, and thank you.
