I dropped out of OpenBSD entirely today, given as my baby daughter is arriving soon... and when she does, she's going to get my free time. And frankly, until then, my wife needs me too. :-) I had been maintaining a few ports; the important ones were accepted by others, and I just de-MAINTAINER'd the rest.
It's not like I'm dropping out of the free software scene entirely; because I still work on Zope at work, and am trying to push to get some more of our internal work released as free software. Oh yeah, and I'm still on the Solaris Package System, even though I am not clear on whether or not anyone else is using it. :-)
