So what does it do I hear some of you asking? Well whoever happens to be on your list, their posts become 'hidden' and by that I mean, it tells you that this particular person has posted and you then have the option to view it or not.
All in all, if anyone understood that paragraph above, what do you think the benefits of this is? I for one think it's good, for the simple reason that you can effectively decide whose posts you actually want to read.
It doesn't mean you have something against the particular person (You might!) but all you'd really be doing is viewing posts for people you DO want to read!
Have I confused you enough yet?
