Yeah, some of my tech friends limit tech content, others don't. Its arbitrary. There's no community convention here, which is something where Google needs to get more proactive. Personally, I post almost everything publicly as I don't want random comments about tech t be lost just because the topic is limited. Also, people can't publicly share limited content. This will indeed spam non-tech family/friends, which is ultimately a big risk for G+'s transition from early adopters to mainstream users. IMO, G+ should have a checkbox against each circle: "posts I share with this circle will be public and searchable" with sufficient warning when you add that circle to a post.
