[Blogging software] may allow blogs to have the same effect on traditional journalism as zines did. Which is to say, a few big-name blog authors will get hired by major media publications to zing up their lame output. They will then become disillusioned and leave to write extremely mannered, hugely popular memoirs based on the experience of raising their orphaned little brother. (Is Glenn Reynolds destined to become the Dave Eggers of blogging? Discuss.)
Also, as it was for the short-lived zine revolution, the simplicity of the new technology has enabled some talented people without formal training to be recognized for their intelligence and wit. I am for this; the rewards of reading something great are well worth the hours of slogging though warblogs, moblogs, etc. Two of my own favorite blogs — The Major Fall, The Minor Lift and (excuse the language) Dong Resin — are put together by proudly unprofessional journalists. I find their content much more reliably informative and hilarious than pretty much anything published by people who get paid to do so.
