I keep a checklist of Book Things to Do. It lists things like where I can post promo items on what day, where I should check/read a blog, where I should blog.
I've been lax lately on the blog thing because blogging is a bit like a black hole. You toss something out there and you're not sure if anyone hears. If a blog falls in a forest and no one is around, does it make a noise?
I regularly do guest blogs for other authors where they give me a topic and I give them a reply. They post it on their blog and voila, it appears. The other day I did a guest blog with another Cerridwen writer and I mentioned some other authors I like to read (ebook authors, all). I didn't tell the authors I was going to mention them, I just did.
Every author sent me an email and thanked me. Their Google alert (an automatic thingie you can set up to track web mentions) had picked up my mention of them.
I like to think that my mention was also picked up by some other readers who may not have been familiar with me or those authors. I want to spread the word, so to speak.
So I guess blogging is worth it. It's like a net that's cast out there. We're not quite sure what we'll catch, but odds are, it'll catch something.
