It's not about what is hip, it's about what is most comfortable. For me, light themes feel like they induce more eye strain. But if a light theme works better for you, then go for it and ignore anyone who judges you for preferring it. Also, whether the theme is light or dark, I would try playing with different contrast levels. Like in a light theme, black on off-white will reduce the amount of overall light being blasted at you and look much more like the page of a book. Or for a dark theme, making the background slightly lighter and the text slightly darker should reduce haloing around the letters.
