Wil Wheaton Review
Star Trek's Wesley Crusher, The Big Bang Theory's (evil) Wil Wheaton, Wil is an icon of geekdom in the TV universe. In addition to his television work he's also acted in YouTube web series, is one of the founders of the Geek and Sundry channel, hosts a show about board games, and is an avid home brewer.
Pro Humble despite success
Wil's work in the Star Trek series has made him an incredibly successful actor. Despite this he remains grounded, encouraging and engaging with his fans, and using his success to help raise the profiles of others.
Pro Home Brewer
OK, so homebrew may not be the best hobby for the younger geeks, but it does show an interest in being creative, recognising value in craft, and enjoying the fruits of your labour; all positive values we should encourage in children.
Pro Don't Be a Dick
Wheaton's law: "Don't be a Dick" is both a rule for conducting yourself on the internet, and on how to live your life in general. This term was coined by and named after Wil Wheaton, and is often quoted in discussions of community sites when people see it being violated.
Con Occasional strong language
Some of the language used by Wil isn't appropriate for younger audiences, so depending on the age of your children and sensitivities of your philosophies, you may need to vet content before recommending it.
