Combine FB Page or Separate?

I have a YouTube channel and a Facebook Page build under the same brand. It's a hobby. I recently started a review blog as part of my hobby and I've been sharing my posts on my YouTube channel's FB page (to a modest 100 followers, so like 2 people who actually care).

What I'm wondering is, should I make a separate page for my review blog and build links to it? Or is it better to have a central hub where I combine the things I do under one brand?

I think that if they're for the same brand, you wouldn't have problems if you choose to combine them. This can save you some time in monitoring, too.
