Has Adrian written on why he left possibly as soon as he was able (assuming that Everyblock was acquired in "summer 2009", and many founders are tied to two year agreements to stay, and he left in August two years later)?
FWIW, he left in August 2012, which would be three years after a summer 2009 acquisition. Also, he founded it back in July 2007...so when he says he "developed an uncontrollable itch to do something new", he probably meant it.
Before Everyblock, he's been a pioneer in utilizing data and non-traditional journalism with news sites, most notably at the LJWorld.com...so he's been in this local online news business for quite a while. I don't think this is your usual case of a founder jumping ship just out of profit motive.
Yes, I don't mess around or BS on my blog. Take it at face value, cause that's how I meant it.
I'd been working on EveryBlock full-time for five years, and I'd maintained chicagocrime.org (the precursor) for two years before that, so I was ready to do something not related to local data or news. My new thing (Soundslice) is completely different.
