I get mixed results, which tells me that the design and content are only parts of the equation... network performance and traffic are obviously others.

And while I wish the site were more tablet-friendly, I also realize that it's basically 1 or 2 guys doing this, on their own initiative, out of their own pocket (not counting possible ad revenue, although my experience is that such income *might* cover monthly expenses, not development time and costs). So I tend to cut them a little slack. I'm trying to make a much smaller site tablet-friendly and discovering it isn't easy for the solo developer...
