I only have a few members who comment on my posts. I would love to have more followers who actually read my posts.
It's not an either/or proposition necessarily, but I think answering the question can show you something about why you are blogging. If you are after raw numbers of followers, you want a wide readership (perhaps for marketing, etc). If you privilege comments, you probably are more interested in community and conversation. One isn't better than the other, but I think identifying what you want is better than comparing yourself to other bloggers.
One other note: some blogs require a "follow" to enter giveaways/contests. These followers tend not to be very active, so if you see a blog with a disproportionate number of followers to comments, this might be a factor.
I much prefer interaction.
I find that the ones with a great number of followers, but no interaction, are usually follow-for-a-follow type of blogs, and a lot of their writing is created for the sake of getting eyeballs on their site. I want readers, just like everyone else, but I also want GOOD readers, or else there's something unfulfilling about even having the comments section open.
Long story short, I love my readers now because they interact, they leave great, insightful comments, and they push me intellectually, which is the point of having a philosophy and social commentary blog.
Comments are a bonus, and I always reply where reply is necessary, but it really is not all that important. If people simply read and enjoy what they are reading that's enough for me.Sorry, I should have supplied a link http://anatheimp.blogspot.com
I have to admit, I set up my blog originally for me to just spill out some of the book related thoughts I had churning around my head.
The numbers of followers wasn't a huge bother to me and to be honest i didn't expect to get much more readership that those who were already friends. I have had some others follow the blog though and I will admit it is good to know that I am at least "entertaining" a few new people that the usual group of people I interact with anyway.
In the end though I do prefer the interaction with people as I think that is part of what a Blog is about. I was so happy to have a few comments poster here and that people were actually commenting on what I had said and offering their own views.
Any just to note, I have started following your blog as I am a bit of a Sci-Fi geek and what you have there looks rather interesting.
