Robert Kalin lists himself as CCO (compliance officer) on Linkedin. It looks like both Haim Schoppik and Chris Maguire are no longer with the company as of August 2008. It looks like Jared Tarbell is also no longer working at Etsy either.
Seeing as the company has raised 8+ rounds, I would hope they had the sense to cash out at least some of their shares.
CCO in this case means Chief Creative Officer. Since he's not listed in the S-1, isn't a member of the board, and hasn't been quoted as speaking on behalf of Etsy in any articles I could find post-2011, I presume that his LinkedIn profile is just rotting away.
I get the impression that he sees himself in the elder statesman phase of his career, given how he is always listed as "the founder of Etsy".
