It's funny. Originally I took Ryan out of public school in order to homeschool him because I saw his interest in reading start to wane. But now that Ry is back in public school for part time math and science, I am finding that he has increased his interest in reading, even more so than when he was exclusively homeschooled. The reason for this is due to his exposure to the kids in public school and their enthusiastic response to the books they are reading in their spare time for enjoyment. These kids share the titles of their favorite books with Ryan and he comes home many days with "must read" books from his friends at school. As a result, Ryan tends to have about four books going at any one time.
For a few years of Ryan's initial homeschooling experience, we were in an unschooling group and many of the radically unschooled kids of the group did not read much and tended to watch TV or play video games all day. This was how they were schooled and due to this, many of the children had poor reading skills or did not read at all and thus really didn't know the enjoyment of reading for pleasure. Consequently, these kids rarely had book suggestions to share and the quality of Ryan's reading was diminished.
All of this is not meant to imply that public school kids read more for pleasure than homeschooled kids, just that some types of homeschoolers, particularly unschoolers, may be getting the short end of the stick because their parents don't encourage reading, or much of anything from their kids. Unschoolers tend to talk as though public school kids hate to read for pleasure and I am just not finding that to be the case.
I am glad that we have found the balance we need
