It's a rather limited form of writing, but if you have some topic that is also covered by Stack Overflow, you can answer questions.
That has the (big, in this context) benefit of directly and immediately showing that a) there is interest in the answer, since someone posted the question; and b) feedback about the quality of your answer, with the option to edit and improve it.
Sure it's bite-sized for the most part, but it is writing in some form. And yes I'm biased, it's easily my number one form of writing (but I don't go around wanting to be a writer, I don't think).
