One of the nicer types of posts I see from time to time are posts where parents return to their questions and provide insight as to what they ended up doing and how it worked out.
It's much more powerful than simply marking one answer as the correct answer.
I'd like to engage in a discussion as to how to encourage people to follow up, but first it seems we should answer the question - should we encourage question askers to follow up?
Of course it will be tempting to discuss ways we could encourage follow up, but please only approach that if it also answers whether we should encourage follow up.
