I agree it would be interesting for someone to do a basic survey of kids who have skipped and how they view it so future parents could have some guidance regarding better ages to skip, problems that did or didn't happen, etc.
Here are a number of anecdotes here, both good and bad.
http://www.accelerationinstitute.org/Personal_Stories/Default.aspxAs for the idea in general, the negative consequences of leaving a kid at his age level has to be weighed against the negative aspects of acceleration. I would give much more weight to the psychologists who work with the kids on a regular basis than the local schools who encounter one PG kid every few years.
As a child, I was both age-stagnated and accelerated several times and I greatly preferred the acceleration. The times I was with my age peers were very lonely and isolating times for me. I now view my time from age 8 to 15 when I was not accelerated as a complete waste of my abilities.
