So, for me it's not about the post length
per se, but rather about the length and regularity of posts. Somehow you manage to post every 3-5 days, somewhat often getting in two installments per week (mad props on that, by the way!), and if each of those is 5000+ words then it amounts to a more significant time investment from the reader. If I knew you'd only post once a week on a specified day I wouldn't think twice about the word count. In fact, there's a good chance I'd be more happy to see a longer post. However, since you get new material up so often, the "long" posts can become a bit much for the casual reader. Again though, all of this is my two cents and can be taken with a grain of salt (or even only a half-grain, if your doctor says you should get less sodium
). If it's not too irksome for you, I'd suggest that you maybe try to set yourself a posting schedule and stick to it for a bit, and if you write more stuff in the meantime, just type it up and have it ready to go for later. It will mean you can take a break at some point if you need to, and can just "phone in" the already finished work without having to produce new stuff. But again, just my thoughts.
