I agree. I think making sure that the feed buttons are highly visible is critical. What you really want, more than random visitors, is subscribers.
I've also found that running contests, giveaways or challenges will increase visitors and subscribers. Plus, you can't discount the importance of commenting on other people's blogs.
I agree with the contest part- definitely helps get comments!! I want to run a contest soon.. but I don't know what or how.
I haven't had a business see my site yet and offer anything, but I was just thinking about buying a little something and giving it away as a prize but I'm not sure if that's silly or not.
BTW- nice blog!
