I read this article: 27+1 Tips on Maintaining a Blog Audience.
Basically, one needs to find the right content, design and maintain interaction with an audience. It reminds me of the time when I had a blog solely for wedding planning - an entry can have 10 comments a day and I received about 100 unique hits a day, not bad for a blog that was only 2 months old. Now, Im maintaining a blog that is all about family life and everything in between. It is hard but I know I can make my blogging better. This blog maintains to be a random blog on whatever useful article I have found online and would like to share to my readers.
