Wow, I'm surprised how much negative sentiment there is out there about blogs. Now, as a disclaimer, I do have a blog, but that being said, I imagine that blogs are no different than any other medium...some are good, some are bad, many are somewhere in between. Some are ethical, some are not, some plagerize, some don't, etc., etc. This same thing could be said of any medium, be it television, newspapers, magazines, etc.
Keep in mind that most blogs, including mine, don't purport to be news or even journalism, but are just a means of communicating with a small group of like minded or interested folks about particular subjects (in my case, sharing tips on good food and drink and occasionally making pithy comments about same)...the internet just allows that communication to go further than was previously possible.
As for me, I regularly read Kevin Erskine's excellent Scotch Blog, http://www.thescotchblog.com
, Dr. Whisky's malt mission, http://www.drwhisky.blogspot.com
, Nonjatta's Japanese whisky blog, http://www.nonjatta.blogspot.com
, and Whiskycast, whiskycast.com (a podcast is nothing more than an audio blog).
