Constructive mathematics

Do you think there would be sufficient interest for articles "how to tell if my proof is constructive" and "how to make constructive proofs". Most proofs are mostly constructive and there is a limited set of "gotchas" that one has to be aware of. Also, proofs which are not constructive can often be made constructive by a simple change. I could write such articles or aticle. Probably it's better to start with a single article and split it up if and when it gets too big.
