Is the internet a reliable source of unbiased information?
It can be (if you search really hard) and know how to spot biases (including your own)
It can be but it requires diligence in searching. I usually look at several sources.
Depends how you use it and what you know about sources and research methods by training off the internet.
It's hard to tell. I often look for the most often reported middle ground.
If you're diligent and care about facts and data. Otherwise, might as well go ask the homeless crazy guy what he thinks.
Certainly not without considering the source of the information.
