[I am asking about promoting a specific app, but this question could be generalized to any app]

I am interested in getting more people interested in zsh on serverfault.com, as I feel it is an extremely powerful and useful shell. Relative to other shells, there aren't a lot of questions on the topic.

There are several very neat, powerful features which not a lot of folks know about, and that are not offered in other shells. Is it taboo to:

1. Post a question of the form "How exactly does feature SUCH-AND-SUCH in zsh work, and what is it used for?"
2. Immediately answer my own question in a way that is clear, concise, and makes people think "Oh wow - that is a great feature. I should try that."

Or is this something that would be encouraged? In one sense, I could see this approach being subjective, kind of a "I think XYZ app is awesome - here's why". But on the other hand, I feel these types of posts could be extremely educational and enlightening.

Can all of you in the community help me get a feel for if this behavior is frowned upon? Thanks!
