I can't speak for anyone else, but I do know that writing a personal blog isn't always comfortable. There are plenty of days I want to delete it all, days I feel vulnerable and like I have written a bunch of crap that no one wants to read. Comments from readers are usually the thing that keeps me from pressing the delete button. I wouldn't take the time to do this if no one read it ya know? I've done journals before, this isn't that.
So when I get comments I know I'm not just writing for the cosmos. I forget I have 'lurkers'. People who read my blog but rarely if ever comment. I'm a lurker myself on many blogs, I can't say why I don't comment, but I am glad everyday when I have a chance to go to those blogs and catch up on their doings.
Having said that, I was recently contacted by Gigi of the roadside scholar blog. She has left a few comments here and there but I had no idea she had a blog since her name wasn't linked to her blog on the comment. Anyhow, she asked if she could write an article about me. I was completely blown away by her post today. Thank you Gigi, I am touched beyond belief by your awesome writing and for giving my art such attention! You can see the article here.
By the way, I was reading her about me page and am even more impressed by her tenacity and love of/for the creative spirit. Hats off to you Gigi!
