Position of hydrogen in the periodic table

I've taken the liberty of reproducing a CHMED-L post from Eric Scerri about hydrogen's position in the periodic table.

The position of hydrogen in the periodic system is a much debated topic. Authors have suggested groups I, VII and even IV over the years. Others opt from removing H from the main body of the table, along with He. The official journal of IUPAC, called Chemistry International, has been running some articles and comments on this issue.
