I do it most of the time. I think chatting about what you've read gives you more insight in the information given in the article.
Similar thing is with all the academical stuff you learn. If you start teaching others what you have learned, even though it is not much, you will get more knowledge in that subject and start to understand it more quickly.
If you mess up when explaining stuff, in the worst case person will ask questions and discussion might arise which is a good way to figure things out. :)
