I used to take new blog submissions via email, but that has changed. Most of the submissions I was getting were for brand new blogs with only a day or two of updates, and I noticed most of those blogs fizzled out and were rarely updated again. I also started getting a lot of blog submissions that turnd out to be nothing more than spam.
Don't worry though, I'm now scouring the web myself looking for new blogs, so if you have a cycling blog with good content and photos, I will eventually find it and list it in the Daily Blogs feed. It will also be listed in the appropiate "Blog Category", which I am currently re-organizing.
One good way to get your blog added is to follow BikeBlogs.com on twitter. I have found Twitter is a great source for new blogs, so I look their often for new ideas.
