What I want to tell you is that there is no case where you want to use it as the formal object and gerund as the real object. As the formal object, it only uses infinitive or object clause as the real object, for example:

Tom made it clear that he agreed. It is a formal object, that is, he agrees to be an object clause as a real object.

I find that talking with you about anything serious is different ... (it is a formal object, and talking with you about anything serious is an infinitive phrase, as a real object)
