I am interested in social media and public relations?

I find it very interesting and I'd love to pursue it.
I have been working on a blog for about 2 years now and have about 111 followers. It's not a lot but I am constantly trying to build the flow so I have something on my side so it's a more likely chance people will come to me to advertise them.
currently I have been going around to people that aren't very well known to the public yet and asking for an interview I could put on my blog where my followers could see them.

Is there any advice from those with experience? I don't have very much knowledge about public relations other than the research I've done online.
