The reason is so much has been going on this month (May 2017). Some health stuff that's all concluded now and significant disruption with an extension being built on my house (I believe it's called an Orangery). Work won't finish on that for about another month but hopefully the really noisy stuff is done now.
Despite all the above, I have been giving thought to where to go next with Blender. I haven't been able to completely focus on it of late with everything that's been happening but that should change now.
I'm planning another live event where I have some pre-considered topics that I want to cover.
I'm also thinking about going into detail on specific topics, such as how and why to use certain modifiers. To that end I've been playing with some of the less well known ones to see if I can find either a novel use, or better understand the thinking of the developers for it.
Anyway, enough rambling, after all it is really all about ...
L'art pour l'art
