Blogs ... do they create isolation?

So last night on “House” this woman lived in and through her blog. She blogged about nearly everything. As soon as something came up in her life, she went to her blog and relied on what she got for feedback to guide her decisions. This in spite of the fact she had a loving boyfriend who wanted to be part of what she was experiencing. Are we investing time on the internet and sometimes neglecting our real life and real people?
