For me, it's also about respecting professional boundaries. I tend to approach your blog as a gift of insight into your life and process - and the things I'm most interested in you don't tend to talk about so I'm not going to ask about them. I have my own boundaries, both personal and professional, and if I want people to respect mine I would be a real ass if I didn't respect other people's.

The authors that I follow on LJ post varying amounts. One (Lj user="sethanikeem"> posts less often than you, but we also know a few people in common so if I happened to make an accidently off comment I feel confident that I have some social capital to make up for that. The other (lupabitch) posts more often than you, but we have a great deal in common and we've actually conversed off LJ a fair amount and we again, have a number of people we know in common. Both of them are people who, if we were going to be in the same town at some point, I would be making a point of getting together to talk in person.

They also post about things that I feel like I have something of value to contribute to occasionally.

passionandsoul I know in person and consider a friend, so I post there as the spirit moves me. susan_wright hardly posts at all anymore, and I actually interact with her more professionally - so her LJ doesn't get much attention.

You fall more into the same category as fd_midori, you post regularly, and you even share more of your private life than she does. But rather like her, I don't have any expectation that you would know me from Adam. And ultimately I do use LJ and other social media to make a connection with other people. My impression (rightly or wrongly) is that we are looking for different levels of personal connection in our social media. There's nothing wrong with that obviously, but it informs my choice of how and when to comment.

But, all that said, if you're looking for more comments then I'll see what I can do to hold up my end of the tacit social contract. ;-)
