So what if the post you are going to comment on leads you to wanting to make your own content around it ? Either by "answering" the post or giving your experience ?

Something like that will be way to much to just be a comment. If you do that, can you comment on the original post and link to your content that you made ?

IE: I have experiences with XYZ also and what I went through / found out is better explained in this article: (Link to your article / video)

Would this be ok ?
