Apart from being a lot of fun (who doesn't enjoy their moment on the soapbox?), writing guest posts is an effective way to reach new people. I've been busy answering interview questions and writing posts on topics close to my heart.
If you have a favourite topic, seek out blogs on the same subject and offer them a guest post. The worst that can happen is they say no. There are plenty of upsides though, for both guest and host. They get free content and extra traffic, and you get a bit of publicity. It's just like one of those symbiotic relationships we had to study in biology.
Some of my recent appearances:
I have a guest post on SFsignal.com : Where's all the junior science fiction?
Yesterday I had a guest post on the Boomerang Books website (George Ivanoff's blog) on the importance of editing for self-published writers.
And a week or so back I had a guest post on the Kids Book Review website which explains why I switched from adult to junior fiction.
Several more to come ... stay tuned!
PS Hal Junior is out!
