I agree, Hani Ni Arashi seems to be catching on. The writing is fiiiinnneee, but it's the art style (Chidori's design is especially unique and cute) that is catching on.
I also tend to like adult life stuff... my personal favorite right now is 2DK, G-pen, Alarm Clock, but that doesn't seem too popular around here, possibly because of its stupid-ass name. But it's got a really likable protagonist and, even though it's not like super deep, it's more complex than your typical fare.
Speaking of which, I second So Do You Want To Go Out, Or...?, which has a very appealing art style. I also like how it's portraying a couple with, like, more real-life problems than most yuri, but in the process features two characters who communicate better than almost any other manga couple I can think of. There's nothing approaching "What are these strange feelings??" here, thank god.
The most popular new thing seems to be Tadorokoro-san, which is pretty fluffy but avoids being too trite.
