According to wikipedia, a blog (a portmanteau of web log) is "a website where entries are written in. 'Blog' can also be used as a verb, meaning to maintain or add content to a blog. Blogs provide commentary or news on a particular subject such as food, politics, or local news; some function as more personal online diaries. A typical blog combines text, images, and links to other blogs, web pages, and other media related to its topic. The ability for readers to leave comments in an interactive format is an important part of many blogs."
I've been visiting a few blogs for a while now. Some of them have a host of great information and discussion. A few pastors that have interesting blogs are:
1. Phil Baker
4. Tony Morgan
