I have no problem with people who charge money for their work—particularly when the prices are reasonable. Even Lamentations of the Flame Princes, which I consider something of a luxury brand* by OSR standards, offers good value in terms of creative inspiration.
For me, though, it's not about popularity or money or the (low) number of comments on my posts. I view the OSR as primarily a gift culture, wherein any individual who freely releases their work increases the wealth of every other member of the community.
The content I've already read on your blogs and PDF's is the reward I want. The content I produce and distribute (and I think this applies for free or fee content given the total revenue of the OSR) is my payment to the community.
For example, I read every one of Dyson Logo's posts. I rarely comment on his posts, but I value them enough that I released a few pages of geomorphs myself.
What the hell is the point of this community if not to inspire each other?
* Although my perception of LofFP as a luxury brand may partially be driven by exchange rates and the cost of overseas shipping.
