It could be that many of the viewers are new users who can't upvote yet, but more than that if the question is generating views there is still the potential for it to be extra useful.
If you're concerned about it, what you can do is take a good look at your question, especially the title. Then think about what related problems might have similar keywords that would drive visitors to the page. Now you can think about how to answer those problems, and finally compose an answer that addresses them. Build up this answer over a few days as you continue to do your research so that the question will be bumped a few times on the "Active Questions" view and your new answer can garner a few upvotes as well.
This not only earns you rep (well-deserved for the extra work going on here), but also drives the new answer up the list for all these late viewers you're drawing. That's a win for everyone.
