Back to Blogging - or trying

I actually read some blogs today. The strange thing is that I read blogs of people I actually know. If you look at my list of favorite blogs I don't actually know any of those people. I have read and followed and even retold stories of blogs I have read but I didn't know anyone that actually blogged. And I wasn't sure I wanted anyone I know reading what I blog. Like a secret journal that can be read by people you don't know. It seems safe. Now I'm thinking that I might want to branch out. That I might want to read those other blogs - that I might want to be part of that group. Then I wonder - what if those girls don't want me reading their blogs. Is there a rule about reading the blogs of people you actually know? I got the one blog address from facebook and it snowballed from there. Do I casually comment on something that is written that I relate to? I'm on totally different ground. I'll let you know how it all works out.
