>Oftentimes these questions are ones that if the developer did more research, he/she could have figured it out.
Have you tried pointing that out to your coworkers? I've had plenty of cases where asking a question gave me a "Sure, here's how you do it. But the next time, be aware you can do X and Y instead." and that taught me to look up stuff first before asking silly questions. I just don't feel like this is a problem related to openspace offices.
The easier it is to ask a question, the lower the quality of those questions.
