Good post by Dylan Stableford at Folio on the viability of advertising models for digital magazines.
In the post he makes the point that "The future of digital magazines belongs to content publishers who use them to capture a unique content niche, crawl into it, define it, dominate it, and attract a unique audience to it. Once that audience is established, advertisers will follow. "
And to make the point he cites the example of digital magazine Avantoure - which he thinks may just cut the mustard commercially.
We shall see..
