It's funny that my "newsletter" reinvigorated my blog a few years ago, but looking at my YTD stats, none of those posts are in my top 10.
That's most likely because I include the entire "newsletter" in the email, while regular posts only have the first few paragraphs.
The "newsletter" posts don't get much search traffic, either, while the more focused ones do, particularly Rogue Trader, Buscaglia, and (oddly) Authors Equity. (Search isn't dead yet!)
