I go through phases of having plenty of time to post and with very little time to post. After many years, I think I've figured out what the big difference is. Obviously stuff at work makes a difference, but as I own a comic and game store, I can sometimes make time at work, so it's only a minor factor. Although a good TV show can cause me to have less screen time for posting, or travel can leave me without wifi (increasingly rare, both in that I haven't gone anywhere lately AND everywhere now has wifi) - that's not quite it either.
No... the big difference is whether my wife is working or not. When she's working, I have plenty of time to do whatever I want - which is run my games here! But when she's off work (like she has been lately) I can make a small commentary post or two (like this one) but to find time to roll a round or post the next big story beat? THAT is difficult!
I'll keep plugging away, though! (And maybe she'll pick up more shifts soon...)
