Many people blogs now a days. but their blogs are plain boring. It's like buying a newspaper with nothing to read. You need to blog what people like to read and not what you want people to read.
I'll be starting my own photoblog soon of all the photos I took ("soon" like 6 months "soon"
)
Blogging is a journal. Not much to say about being a webmaster unless your blog site is a hit like jeffooi's. That's because he's writing what people like to read his mind.
