That's true. Content analysis is nice in that it's a way to quantify and bring more rigor to analyzing qualitative data. There are many ways t carry out content analysis as well (e.g., CQR, or just coding). I'm partial to Denzin and Lincoln's book the Landscae of Qualitative Research.
If there is some coding scheme you're doing with your outcomes variable as well, you could look at some simple cross tabs to see where chosen language intersects with your outcome variable. You could also calculate odds ratios to see the liklihood of a chosen language and the outcomes of interest. Not very conclusive stats, but may point you in a direction to theory building, etc. Just a few ideas
