I only "sort of" came here for the money... I was ready to resume "general interest" blogging, and this seemed attractive because I figured it would be a lot easier than setting up a blog with Google Adsense links and Amazon links for monetization.
Not only has that been true, but the income stream here has been far more immediate... Adsense/Amazon typically take a year or more to gain any "traction" on a new blog.
So, getting back to the "quality" part... I pretty much come from the school of thought that it REQUIRES quality content to drive traffic and a following, which leads to benefits. I won't post crap, because I won't read crap... and I won't support crap.
