The challenge of organic modeling is not for the faint of heart. Terms like edge loop, quads, stars, n-gons, topology, etc. are used casually and many new modelers may not understand the terms or the workflow concepts necessary to produce a clean and/or animateable model.
SomeArtist a frequent poster of the excellent Subdivisionmodeling forum has started a blog that contains a wide assortment of knowledge from techniques to concepts regarding 3D modeling. The website is appropriately titled "The Journey into 3D modeling - State of mind, Wisdom and Inspiration". You can find SomeArtist's website here.
Some other links with some excellent discussion started by SomeArtist on modeling techniques can be found at the Subdivisionmodeling forum:
