Promote your blog, Places to submit your RSS
I did some searching and found some places to submit my rss feed. It is also a good idea to find people at mybloglog that have sites in your same area and add them to your contacts and join their communities. You will find some great sites you never knew about and also increase your exposure. When I did this I got a big spike in subscribers to my rss feed.
