Suzanne Falter-Barns does a great job addressing the issue of blogs vs. e-newsletters here. Blogs are more immediate, faster, easier, less formal, and with comments, more interactive.
In the case of WebMarketCentral, I thought about what my newsletter would include if I wrote one: a link to my latest blog posting, e-commerce news and Web marketing news headlines, a sponsor or two, and some humor. Since pretty much all of that is already available on the site -- generally with RSS feeds as well -- I decided, instead of writing a newsletter every week, I would offer a build-your-own-newsletter capability on the site. It won't have an elegant format, but it will get the job done. And it won't clutter up your in-box.
Oh, and another highly useful marketing site: Mike's Marketing Tools offers an excellent search engine rank checking tool that lets you quickly and easily see how well your site shows up, for any search term you specify, on 10 leading search engines. Very slick.
