Blogging is a tough business, and it's only getting tougher--projected drops in advertising could soon rewire the blogosphere.

Even book executives are pondering the future of this mysterious art. Debbie Stier, Associate Publisher at HarperStudio, confessed that she never imagined what sort of mental gymnastics authors endured following her digital evangelism:

"First of all, it's really hard. Do you know how many times I told authors, without batting an eye, 'Blog Blog Blog.' I feel so guilty now that I've discovered how hard it is to be 'on' when someone says 'go.'"

After a few weeks in the driver's seat of a blog, Stier is looking for blogging advice from the Internets. GalleyCat suggests this RSS feed primer from Yen Cheong. What do you think? Help Stier and her authors answer the question: "What makes a good blog?"

Update: AgencySpy landed an interview with Gawker publisher Nick Denton, discussing layoffs and the future of blogs.
