And the tech industry's revolving door keeps on turning. Former webOS developer relations lead Richard Kerris left HP last week (after only nine months on the job) with a new home on the horizon — Nokia. Earlier this morning Nokia's SVP of Development Marco Argenti tweeted that he was happy to announce that Kerris would be joining his team as Global Head of Developer Relations. Seems like a good time for Kerris to be joining the fold, at least considering the Windows Phone momentum out of Nokia World this week, but let's just hope — for his sake and ours! — that Nokia's future is stabler than that of Palm and webOS.
