I've been blogging for a few years now and a few months on "nickpalmbyblog.com." I enjoy reading other people's blogs and have been doing this for much longer than I've even had a blog; however, I find a problem and that is "how can I consume all this great content without having to waste time going and checking out people's pages?"
When email subscriptions got big I started signing up on peoples blogs. I have one on my blog at the top right of all the pages near the rss feeds. I really enjoy waking up early each morning and being able to flip through 10-20 emails from blogs and get the content I want and delete them. Saving time and keeping each day being feed from sources I'm familiar with and enjoy.
So when I come across a great blog and don't see an email subscription through feedburner or feedblitz I get turned off and fusturated and usually don't return to their site again even if the content is great. I just simply don't have the time to surf and dork around on people's blogs. If you have a blog there are plently of people who love this feature, so use it, and please your readers!
