I didn't realize there were so many different kinds of writing and editing blogs until I asked people to send me their URLs.
There's Amy Grech's Crimson Screams, which seems like a series of Twitter tweets. In fact, there's an entry just called Tweets (http://amygrech.livejournal.com/99852.html).
There's Boomers Write, a site where people my age spill their guts about various subjects near and dear to them. Here's the page on things to consider before you write -- http://www.boomers-write.com/writinggenres.html.
Ann Wilkes has her sci-fi site, Science Fiction Musings, which has the subhead Science Fiction and Other Oddysseys. I assume the latter is an homage to Arthur C. Clarke's 2001: A Space Odyssey. The most recent entry was an interview with Robert J. Sawyer (http://sciencefictionmusings.blogspot.com/2009/04/interview-with-robert-j-sawyer.html). I'll have to come back to this site; I love sci-fi.
Barbara Hales gives advice in her blog The Write Treatment. She wrote a nice blog on how to sell a product without being obvious about it (http://thewritetreatment.com/blog/?p=53), so I'll probably have to come back here, too.
Cheryl Semick writes about various subjects in her blog Writings about Writing. Her most recent blog was about the need for white space in a blog (http://ccsemick.wordpress.com/2009/04/15/let-there-be-white-space/).
Gotta go. More later.
