I'm not much interested myself in reading about the learning process of how to do things online, how to blog, etc. However, many others are, so I expect if you write about it often and well you will find an audience. I don't think you will find better technical advice than you get from TimeThief, who is well-known in these forums. She also writes and maintains more than one successful blog.
My own goal in blogging is just to become a better, more effective writer on topics I have interest and experience in - philosophy and the arts.
I do hope you enjoy your blogging experience, and wish you the best of luck.
