For all would-be, new or shy bloggers, Lutheran or not, the Aardvark gives great advice for developing and furthering your blog. Here's a little sample of his advice:
No Blog Is an Island
If you want to reach others, it helps to join with others. The easiest way is through some form of blogrolling. You'll notice that the Alley has a rather large blogroll. This is intentional; if we were all professionals, I'd call it professional courtesy. I don't read all the blogs on my Confessional Lutheran blogroll every day, but I do keep an eye on them. I list them not because I agree with everything they say in total, but because we are theological brothers and sisters and because I've learned to trust the output to be interesting and edifying. You may favor certain blogs over others; this is fine. Give them top billing or a bright color scheme in your blogroll. But don't forget to list some of the others who are plugging away, making their own contributions to Lutheranism in cyberspace in their own way. Especially, consider reciprocal links whenever possible.
Reciprocal blogrolling is the backbone of increased readership.
