Funkie, You'd be suprised by those fancy coral magazines. They pretty in depth looks at a number of issues, from specific corals, to equipment, to say the Great Barrier Reefs. I've found that the magazine Coral puts out a good magazine that can give you some scientific insight. However, I would suggest that the magazine find at least a couple more authors to cycle in. You may have better luck reading scientific journals. I don't know the names of any, but I'll check for you tomorrow.
In regards to fads in the reef keeping hobby, IMHO, none of them are new, and in fact most of our practices that have either cycled in or out of popularity for about the last 60 years. Foam fractionation, DSBs, phosban reactors, etc. have been around for a long time, just not consistently popular, or available.
I too would like to see advancements in our reef keeping hobby.
On a side note: in the 1880 and 1890's in England, aristocratic women often kept anenomes in small glass cages as a decoration. The anenome would often live for a month and then perish.
