This post is right on time! I have been thinking about this is issue as well. Relationship building here is a little more challenging as you are getting to know total strangers, but that's the point right? One of the limitations of youtube, in my opinion, is that your posts mainly reach your friends and family, some of which are already quite aware of what you do and think about already. With that being said it is a slow process. my communication on here seems to be limited to a few comments back and forth then nothing. Time will tell...
