About the old poll, never done, but maybe it will be a good idea.
About the new poll, well I pick up new manga when I'm bored, so I watch the cover and if I like it I read the summary. If I can't find anything I pick up something randomly, and wish it's good.

The majority must not care about New Year's Resolutions anymore.

There are many reasons why I would try a new series, not just one. The most common reason is because I've caught up or finished reading the many series I started. I chose "The summary looks interesting" because that would be the most common reason to try a new series, out of the choices in the poll. Many of the other choices also apply to me, I usually search for a new series through genres, ratings, mangaka's older or newer works and simply clicking on it from the "releases" page. This poll is a bit too broad and there's no "all of the above" choice.

Why doesn't the poll have the answer "because it's my favorite genre"? THAT'S the reason why I read new series. I always only read shoujo/josei/romance series. And I usually give chance to ALL new series of those genres.

For me it's a mixture of art (cover page) and the summary. Impossible to choose between the two. If the summary is good but the art looks horrible then I may skip over it (and the reverse is true as well).

I usually read a new series (taking new as in I've never seen an anime of it either) because the summary makes it sound interesting. It's usually anime that tricks me with the art.

Abt the new series, I didn't reply bc there isn't option "I collect everything from this genre/scanlation team". For me this is the reason that drives me reading a new title.

Abt the old poll, I really don't know what these New Year Resolutions are but I suppose they are kinda promises ppl make to themselves.

With usually as a key to the question I voted "It's the same author of a series I like". I think this answer is the most right for ppl who choose a title bc of the genre they like.

I don't usually pick a series for one reason. Usually its a combination of summary, reader reviews and artwork. If everything sounds and looks bad then its usually not worth my time. The opposite generally holds true too (but not always, I sometimes disagree with the group).
