Ohio Genealogy News with extended on-line versions!

The excellent genealogy newsmagazine Ohio Genealogy News has made an improvement: in addition to its print publication, it now provides on-line extended versions of two articles in the current issue, one on the Western Reserve and the other on Geauga County.

I know that the Indiana Historical Society's twice-yearly The Hoosier Genealogist: Connections publishes supplemental data on-line, coordinated with articles published in the hard copy.

I wonder why none of the top-line genealogy journals -- all seriously constrained for space by the cost of paper -- have not chosen this route. Is there a downside?
