One of the goals of a typical blogger is to get people to faithfully read their blog posts. The easiest way to keep up with a particular blogger is to "follow" their blog and get an email update whenever a new post is added.
A few really serious bloggers make a living from ads or products and/or services they offer via their blog, but for most of us, being read is the only form of compensation we receive. (Hint: comments are always welcome. They're kind of like applause after a performance, letting us know you didn't fall asleep halfway through.)
And most bloggers read/follow other blogs. That makes sense: those who love to write generally like to read, too.
I don't have a long list of blogs I follow, but there are those that I do keep up with - some of them are listed on my blog. (Sharing the good news and all that.) Unfortunately, I have discovered that I am the proverbial "kiss of death" for many an unsuspecting blogger. As soon as I start following, they stop writing. So if I don't follow your blog, please don't take it personally - I'm just trying to protect your writing muse.
Happy blogging,
