I always feel these are worth the wait, because when you update there's always so much new content! Used to follow someone who would update very quickly, but it was always "two minor things were added" or "added one scene that probably took 2 minutes to deal with", I suppose he wanted to update as he did stuff, but it seemed excessive because from A to B was so minimal. I'd much rather "OK, yeah, it took 3 months, but there's 3 hours of new content!" :)
I would love to think it's worth the wait! Probably not business wise, but I definitely get the disappointment of a tiny, underwhelming update after waiting. People just read a lot faster than I can write lol, 8 hours of writing for something you can read in 10 minutes. Don't think there's a way to fix that, as much as I wish there was.
