Tim Parkin who did the work on comparing landscapes shot with 8X10, 4X5, IQ 180 and even the Sony 900 earlier this year continues to publish the online magazine On Landscape.
It's quite expensive and I think many will reject it out of hand without thinking about just what it's giving us.
There have been technical articles like the above - a huge and very useful achievement, as well as quite indepth discussions by real photographers on the art of photography - as well as book reviews and portfolios.
Given the videos alone, and coming every couple of weeks as it does, this makes the sign up cost pretty darn reasonable - $100 approx. for 26 issues - but that's $4 an issue, no advertizing to pile through, useful stuff in every issue - I think well worth the expense. It's nicely set up so you can see the beginning of many of the articles without signing up - so do check it out, and consider subscribing as I have done.
