I have been blogging a long time and I have found that the secret to a good blog is content, personality and honesty. People I think want to see something real and I try to be that in every post. Another secret is to keep on blogging…the more you do it the better you get at it.
Finding community and like-minded people can be a huge help too although you do find some folks who are heavy on the criticism.
Like anything it is good to make it fun and something that allows for expression and reflection. You might even change the world by your words and images. Blogging is awesome and I encourage you to be the star of your own blog.
