Yes, yes, its a good thing! (make a separate blog for that).
I just prefer to post once a day, and quite the opposite - have too much stuff to be posted, have to choose and limit myself. As a photographer, I have too much stuff captured, and not enough time to edit it and present in the best, more quality way ... translating texts from Russian to English (in a good way, without relying on Google' help) swallows sufficient amounts of time, too. I spent half my day yesterday, shaping a post about my best Steemian friends (did you take part in it, by the way? let me check). I wish each day had at least 26 hours! 24 is not enought...
Subjects for posting can be various, but having a few challenges is a great thing, it stimulates and directs you too, in a good way :P
