That’s an interesting topic (one that could get a topic by itself I guess). In fact I do not post a lot to horizontalpitch, it’s on a “when I have some time and energy left” basis. But I guess I enjoy writing about things sometimes, so the blog is still there.
I asked myself often if that is really enough to sustain the blog. Will enough people come back to read what I write, when I have months, even a year of inactitivy between one post and the next? People are used to multiple daily updates, actually I guess we’re getting used to being continuosly flooded with updates, so the way I do it is certainly going against the stream.
I guess that’s why I really appreciate those blogs and podcasts that really take the time and care to write/create content. Which of course doesn’t really exclude more frequently posting blogs.
This said, I would totally welcome articles on process, no matter if they be long or short, more in-depth or more supposed to make you curious or inpire you to try something new. I would also not care if they’d just pop up in my RSS feed once in a while.
And btw. I do like @Ethan_Hein’s blog http://www.ethanhein.com/wp/. He does writes a lot about music theory, and composition and process are kind of part of that.
