I never did get around to my advice post, mainly because I was out of town most of the month. However, it was also hard to say what I would have added given all the great posts that other bloggers put out. Some of my favorites were Anjin's general advice on how to get pageviews (Blue Kae had another good general advice post I can't link now for some reason), Tesh's poignant piece on blogging as a social activity, Rowan's duo on the mechanical aspects of setting up blogger (I actually tweaked my settings after reading both of those), and the part of MMOgamerchick's post where she explains why she usually answers all of her comments (I couldn't agree more).
During the course of the month, I did spend some time thinking about what I consider the single most important piece of advice I would give. I think it would be something along the lines of "Write about your passion." Write what you'd like to read, what you want to say, and what you feel needs to be said. Blogging is a labor of love more than anything. Very few of us are ever going to reach the popularity of Tobold, and even the Tobold's by and large aren't making any money blogging. The only reason in the world to blog is because you have something that you want to express, and thoughts and experiences you want to preserve.
For me this blog is one part diary, one part personal soapbox. Of course like all bloggers I want to be read, or else these posts would be unpublished Word documents on a random desktop. But I'd say creating something you are happy with and that expresses your voice is probably the single most important goal to have as a blogger. Whether your blog attracts a small audience or a huge audience, if years from now you can look back on certain posts and think "I made that, I'm happy with it and I'm glad it's out there on the web" I'd say you have succeeded.
